I got a Blackberry Storm 1 on the day it released. It wasn't a bad phone initially, but it needed a lot of work to get to a point where the OS was stable and the phone was actually functional. Once it got to that point, the OS wasn't bad, but was still a little laggy and unresponsive at times.
The first generation Sure Press is absolutely miserable. The screen is sitting on one button which is right in the middle. The further you would get from that center point, the worse it would function. If for some reason you had to press something that was in the extreme corners, it's hit or miss if it would function. Plus, those corners would flex. In addition, since it's on that center point, the screen has a really annoying wiggle to it. There's enough of a gap between the edges of the screen and the phone that you can move the screen. Eventually, my Storm stopped working. I was sent multiple replacements, but each replacement was worse than the preceding phone, and it was all due to the screen and non-functioning edges. Eventually I swapped out to a Tour, but even the Tour was goofy. I ended up picking up a Droid on eBay just to get out of having to rely on an unreliable blackberry. Compared to the Storm 1, the Droid is light years ahead of the Blackberry. The screen is vastly superior, the operating system is a dream, the internet browser is incredible, and the marketplace is far superior.
If your priority is email and messaging, a Blackberry is a great phone. But skip the Storm 1. It's the worst of touch screens mixed with the worst of blackberry operating systems. Avoid it like the plague. Stick to your Droid. It'll save you on a lot of aggravation.
