If you had to choose one device, which smartphone would you have today at work and why?

Either the Samsung Galaxy II or the new HTC Velocity. Both are solid, great phones, great screen and resolution.
On top of that, all phones work well with Exchange email and support POP3 for other mail servers.

Really? When I'm at work, I'm at work and when I'm away from work, I want to be away. So the office "old fashioned" wired phone is fine at the office. I still look at phones as being mostly about voice communications, not data. If I "need" internet-to-go, I would probably go with some kind of tablet.

I like the Samsung Epic (Galaxy phone) because of the phone size which is slightly larger, 4G capability, Android and mostly because it is till the only 4G phone with a Querty keyboard which is great for texting and emailing. Not sure why other newer smartphones do not come with Querty keyboards.

Perhaps the question really needs to reworded? We have an arsenal of devices available to us and then limited to smartphones?

For smartphone, having used Palm, iPhone, Windows, and BlackBerry -- Windows, hands down... none of them are perfect but overall Windows was better in my experience as I could be more productive. With iphone - I felt like I had to go through a maze to get where I wanted to (reflecting very much like the work environment at Apple), It's too bad MS has been so slow in getting in this arena...

I like my iPhone 4 very much for it's great camera and useful, relevant apps. I only wish it was compatible with Flash.

I'm currently using a Motorola Droid 4. I'm fairly pleased with it, though it's taken some getting used to coming from my HTC Thunderbolt.

Interesting question, pity it is so narrow that it misses two of the major considerations in selecting a Smartphone.

To answer the question. Over the past 4 years I’ve used the iPhone, the Samsung Galaxy and various Motorola offerings.
My favorite is the Samsung Galaxy. It is more durable than the iPhone 3, the call quality is acceptable and the range of applications available is deep enough that I can share applications and data between my Smartphone and my laptop. I find the virtual keyboard on the Samsung to be good enough for most ways I use the phone. Now I find the physical keyboard on some of the Blackberry phones clumsy.

The question that is way more important than the Smartphone. Can I use my phone from my current location? Now, when I need to? Let me give some detail around that statement.

I live and work in the San Francisco Bay Area. There are still many locations in this area where one or more carriers cannot consistently deliver reliable service. So part of the selection process for a new phone is the ability of the carrier I’m using today to deliver acceptable service. Texting is always more reliable than voice calls.

As we move to a virtual work place and a much extended work day the ability to reliably make high quality calls crucial, otherwise it is back to the office.

The other important selection criteria are the ability and ease of accessing regional services at a reasonable cost when I travel. Unlocked GSM phones and the ability to pickup local SIM cards and a local number in a country is a great benefit. These criteria drove me to select the Samsung over the iPhone when I upgraded my phone 2 year ago. Today?

At my work we have a mix of Blackberry, IPhone and Droid. Like Robert I have not been a big fan of IPhone, preferring the Droid instead. The users in my company travel internationally quite a bit and I have come to the realization that IPhone is the best suited for our needs. The main reasons being battery life and the ease at which it connects to roaming network internationally. Whenever a user with a Droid travels abroad they are sure to run into issues where the phone does not connect unless rebooted it several times.

Like Robert and TJ, I not a big fan of iPhone, would use my Droid for better operating system usability and especially for the fact Google does not limit Apps to what they think is good like Apple does, instead of letting me decide.(I am in the manufacturing/industrial industry so a company like Apple being so disconnected from it users, has no idea what App is of value to me and shouldn't limit my choices.) Because my company is developing apps for our industry I also had to buy and use iPad, as well as my Google Zoom. Something as obvious as a browser icon, multiple windows, browser back button being left out of OS, caused me to throw iPad in drawer never to be used again, except for testing our apps they may possibly get approved by Apple in the future. But off my soap box and onto some good points to consider when answering the question...
1. Most users do not purchase smart phone based on work, it is personal usage for buying decision, then they use at work whatever they already own.
2. Depends on type of work, place of work, country and industry. (like in manufacturing plant with the metal ceilings.)
3. First vendor to place IR transmitter back in smart phone and add RFID reading technology built in will most likely be more popular in the industrial workplace.

iPhone wins because it has more apps.

I replaced my iPhone with an HTC Evo, and I've enjoyed the tighter google integration and some early adopter apps (such as Swype.) But there are more apps built for iOS, including work specific apps, because the ecosystem is more robust. Until Android solves this (if they do), the iPhone has more function and form.

I use a BlackBerry simply because the Bold model gives me up to 2 days of battery life (if I am under a data plan like social and email) or 3 days when I am not. I always use the password keeper app for all the accounts I created including personal; and the organizer to set appointments and tasks.

I once had a Samsung Galaxy S2 but the battery life only lasts a day. While it’s great for web browsing and Gmail, it’s a drag to charge it especially when you’re out of the office and you just need to send text messages.

Call quality – BlackBerry is outstanding. I’ve used other phones in the past, but I really appreciate BlackBerry’s strong signal even when I’m on GPRS or EDGE mode. I like Samsung as a dual-core phone for its speed but I can’t hear the caller on the other end (even when you’re in an open area).

I don’t want to sweat the small stuff for anything work-related. Everyone can have an iPhone and Android, and tell me they’re way much better as a business phone, but I’m fine with the experience I get from a BlackBerry.

Forgot to share something else the first time here....

For international travel, though old, I find the Motorola Razor QuadBand best -- can be used in any country. If you're planning on traveling anytime soon, every country carries theif signal in one of 4 bands (hence the QuadBand nomer). With this phone, I just buy a SIMS card in the country I am in, and the phone picks up the proper frequency. Don't have to worry about roaming fees and surprise bills waiting for me when I get back home. Bought this phone after a colleague racked up a $846 bill in ONE day as she forgot to turn of roaming and set it to wi-fi only... ouch...

I am glad that you asked this question. I hope someone will read my input and create
the next generation of Blackberries to suit my fancy.

I like the Apple iPhone for aesthetics and simplicity.
The Blackberry, by far, is a better phone. Also, I can BBM on it. However, the keyboard
turns me off. It is too busy and the keys on the type pad are too tiny and ugly. If I can take
the face and keyboard of the Apple iphone and stick it on the Blackberry, I would have the perfect phone. Presently, I own a Motorola for the simple reason that I cannot find a Blackberry that suits my fancy. Cosmetics and simplicity is what I am all about.
Until I can find a Blackberry that is as attractive as the iphone and powerful as the blackberry, I will stick with my Motorola.

I have been using Android based phone and don't have any complaints so far. I have heard about BB being a better choice for office communication usage but I have not used it so far due to its closed environment.

For business use, I've found that the latest Window Phone 7.5 on a 4.0-4.5" screen suites my needs very nicely. Word, Excel, and Powerpoint, as well as Outlook work seamlessly with all my Microsoft programs and I can use my phone as a hotspot for my laptop without having to jailbreak the phone. In addition, having spare batteries really comes in handy when traveling. Apps that are relevant are plentiful and data usage (especially with Outlook) is very efficient - more so that Android and IOS systems.

What away from work? Who developed that idea??? Just kidding.

My station/comp has 5 screens and in the middle of that is my game comp and underneath is my server for playtime. To my left is my iPad and to my right a laptop.

I really like going out with my iPad. When I walk along the street in video mode life becomes like widescreen TV and my pad is the capsule. It is so cool to have instant (life) replay and record in front and behind at the same time.

Robert makes a good point about having sufficient exposure to the available options.

I've had the benefit of evaluating different phones because I have friends with almost every type of smartphone. I recently selected a Motorola Droid RAZR as an upgrade from an original Motorola Droid. With Swype, I don't have any need for a physical keyboard (which is what I thought I needed when I went after the Droid, two years ago) and I love the reasonably large screen and versatile OS.

While I will agree that the Blackberry is still the fastest email input device for me, I do so much more with my phone, that this one criterion does not have enough weight. And the Android platform has more than enough quality apps to keep me going.

The Verizon LTE network has been great for me.

I'm also keeping my eye on the Windows Phone market, and will reevaluate them when the newer hardware becomes available.

I use iPhone, this is my only phone at work. I do not have a desk phone or others. This works perfect. I have it all the time with me (when I want), access to agenda, e-mail and a wide range of APP's. And it is Apple, which means less virus...

BlackBerry Curve... is the best i would say... not only it is light and small but it also has a reliable and fast push mail feature for quick message delivery

Blackberry because of its business integration and remote management features, e.g. wipe from our server. Some provider management for other phones, but not as accessible to me. ATT and Verizon can remote wipe iPhones. Android has legal issues over hijacking Java from Oracle (same as Microsoft JavaVM, Microsoft lost to Sun, now owned by Oracle). Android Java presentation interface crashes often, not as stable as Java Micro Edition from Oracle(Sun). Lack of App security.

i would go for BB

The BlackBerry.
For example, having sampled several of the Smartphone offerings available at present, the E-Mail facility on the BlackBerry is very user-friendly and reliable. The WAP reception is consistent/uninterrupted and my own experiences with it are that is doesn't have freezing issues as is common with a lot of the other Smartphones.

I-phone by apple would be my choice because of it's cutting edge technology.
