I'll give you the same response I put up on Crackberry.....
I first bought the Storm 2 hoping for much better than I got with Storm 1, and I absolutely did. It is definitely a hardware upgrade on a couple levels. Proximity sensor, memory, screen, and of course much faster which (about time) you could say the same now with Storm 1's upgrade.
Storm 2 is a great device. It gives you Wifi, that wonderful Blackberry Email, Blackberry Messenger. It has excellent graphics of course with the very simple, and sometimes unfortunately very old Blackberry Operating system format which delivers ultra slow internet and IMHO programs that could use a bit of an update. You really do get a great device with the Storm 2, it is definitely what the Storm should had been to begin with. The best thing on its release is you are not seeing NEARLY the same amount of problems with this device as you were the first.
I unfortunately found the Blackberry platform a bit old, I felt they threw the platform onto a nice touchscreen, updated a few apps to work with that touchscreen and landscape and released it without anything really astonishingly new. I got sick of the ridiculously slow internet and found Wifi on it to be just as slow. Please keep in mind, this is just my opinion, I am not bashing anything, just posting for comparison sake.
I exchanged the Storm 2 for a Droid, and after the learning curve, I am loving it. You will definitely have to take some time with the hard keyboard and get used to it. It is a bit cramped, but once you know where to press on the keys, you will find yourself up to par with it, which was one of the biggest reasons for my switch, I like being able to type on a touchscreen without losing 2/3 of the screen to look at. With the D-Pad, it makes editing what I wrote 1,000 times better than having to flick through 1/3 of the screen to find what I needed to touch the exact spot which rarely happened and fix it from there....it's a lot to go through to fix one typo. The screen is gorgeous, I like the ability to configure everything to my liking, I love the widgets, the phone itself sounds great, and of course the $10 I saved per month on Navigation was a nice bonus too. I also like having a nice large choice of applications to download, there is much to make the Droid experience better and better.
What does Storm 2 have that Droid dosen't? Easier to input Calendar events....I could push on the Time in Storm 2 and add the event on that 1 screen. Droid I have to push the time slot, and go into the screen not bad....but a couple extra steps.
More options in the Navigation, I could use simple or fastest route, choose highways or sideroads, Google Nav just takes you there.
The Camera.....nice Autofocus with no noise, great photos, and has has image stabilization, if Droid has it, it dosent show.....however, I do feel Droid's camera will improve on software update....judging by the video camera, it certainly isn't the hardware that causes the problems.
Hope that helps....good luck with your decision, and of course, please let us know what you decide.
Ultimately go to the store and try them both....
