what is so great about the Galaxy? Maybe I should replace my HTC.
For me, the big, BIG screen. It's fast, it's bright, and it's readable.
It can also be a bit of a pain, ergonomically speaking - I had the same problem with my first iPhone, it just took some getting used to. The real reason I like it is because I'm an IT geek and I can root it and do whatever I want afterward. Custom ROM, choice of OS; it's pretty nice if you like that sort of thing.
