D1 to gnex
love this phone.. rooted but haven't loaded up any roms yet. ics is just so nice stock. i do have some of the cool boot animations thou.
as for big, my girl has a t-bolt and my nex might be a tad longer, like a 1/4in. but same width and why thinner and with its curve. it fits in my pocket much nicer than even my thick boxy D1 did. so everything you hear about a gnex being to big is just plain hype. if you like the 4.3in screen phones. this phone is a tab bigger but feel smaller and handles better on a daily bases.
as for a real keyboard. i do miss having one a bit, but not the D1's really. it was never a great keyboard. i miss my old sidekick 3's keyboard. now that keyboard got **** done. but really, try a few different keyboards, i use swiftkeyx and you will be fine pretty quickly.
