I actually went to Verizon today to look at the Droid X, as I want to try and actually sample products before writing them off (as I admittedly do sometimes) and was disappointed that I couldn't actually use one. I've never spent much time in a Verizon store, so I wasn't aware that they didn't have working models, and only "outer shell" non-working plastic versions of the phones, to get a feel for the size, etc. This may not be standard practice, but being use to Apple's "try before you buy" policy, I wasn't expecting that haha.
On a somewhat related note, when I went to Best Buy a couple of weeks ago, they had the HTC Evo 4G to try, and so I gave it a whirl. I have to say that I wasn't captivated much, but that I did somewhat like the idea of "video wallpaper". It reminded me of the dynamic themes used on the PS3, and I could see that being a neat implementation on the iPhone 4 if done correctly. This of course is a purely aesthetic perk, so I'm sure it isn't something they would be ultra concerned with at the present, but the option would be cool. I have the stock "blue orb" background right now, I could see that being even cooler if the orbs slowly moved around in the background, etc. Some people would HATE this I'm sure, so it would only need to be an option 🙂
