I had the curve before the one you had (8800 maybe)? it was the small, girly one, but up to that point i had 2 nextels (yes, the big clunky ones) and then my first "smart-ish" phone was that flip keyboard one with robots...forget the name, but they used to say "don't call it a phone". then i got the 8800, and now i have a bold like you.
i drop phones / hit things with phones constantly, and sadly the sturdiness of the phone is a big feature for me. i have the bold now, and this thing is rock solid compared to how flimsy an iphone is.
plus i don't look like i suck cocks everywhere by holding my big iphone to show the world.
i'll stick to blackberry for now. the only other option might be something android related in teh future, but i doubt it.
