As stated earlier, try it and see what the BB is all about.
My personal opinion is this, you can get a device that you may be unhappy with just to save a few bucks but to me that's the same as settling. If you try the BB and don't like it or have any doubts, I'd stick with the iPhone. If it's like most big companies, and it's a company phone, much like I had with Lockheed, then it's paid for, if you still have to pay part of the bill, then I say use what you like.
Sure the BB has some features that the iPhone doesn't have, but it has one feature that I despise over all else.... THAT STUPID ROLL BALL! It's not even like a might mouse roll ball, it just rolls over all clickable surfaces and is annoying as all get out. You may get used to it, I might have gotten use to it, I told my company "Get me a BB that has a touch screen or no deal" and I kept my Treo until my iPhone.
If I have to pay some/part/or all of the bill, then damn if I'm gonna get a device I'll be happy with and can do more that just work on it. If they're flipping the bill, then tell them gimmi the BB but I'm keeping my iPhone. Sounds like your flipping some of the bill so keep/get the device that's gonna make your life easier both outside and at work and that you'll be happy with.
Don't get it to settle and save a few bucks.
Go to the ATT store or any cell phone store and check out the BB's and look at their website and see if anything catches your eye to try out. We can sit around and post "get this, get that" all day long but it's you that has to do the investigating as to what to get or keep.
