I thought my Droid was too big when I got it. At 3.7" it was one of the biggest phones at the time (the only one I can think that was bigger was the HTC HD2). When I heard there were 4-4.3" phones coming out, I figured that was too large. But after doing an awful lot of playing with these phones and starting to rely on my phone for more and more internet and media, I really kinda like the sound of 4.5".
One thing I loved about the Charge was that it's size was actually just right for my hand. I could on thumb type quite naturally on it (even more so than the same size TB, Revo, and DX2). Now, I'm thinking 4.5" might be the way for me to go.
