the storm2 is an awesome device. I owned it previous to the droid and still own it because i can't let go of such a great device. I love my blackberry, and i like my droid. My droid is a fancy toy with great apps and an amazing browser and a nifty screen setup. The storm2 is an email nerds fantasy (like me). The screen is light-years ahead of the s1.
As for the tour, I had that phone also. It was nice, a pretty good keyboard, but it can't stand up to the storm2 or droid for the most part.
I still have my four but I don't think ill be using it anytime soon. The tour was a great phone with little or no issues for me and so is the Droid. But I have to say the Droid is much more fun to use and is much faster at browsing the web and the screen is amazing.
I don't miss my tour even a little. The experience with the Droid is light years better. The only thing I kinda miss is the keyboard shortcuts, but I've only thought about it once or twice. Ive never missed the storm 1. I got to the point where I hated that POS.
I have my tour still. I won't be going back to it for my daily driver. I'm hanging on to it for when I travel internationally. Otherwise there's nothing really that would pull me away from my droid, especially now that I've moved a lot of my friends away from BBM and to Gtalk.
I have to be honest and yes, I really did miss my Storm 1.................for the week I had to use an LG Env3. Definitely not since having the Droid......Can't really say about the S2 except that from what I've seen playing with it I would definitely gotten it where the Droid not around.
