I switched from a droid X to a facinate... While i loved the Typing space. and the sturdiness feel of it. the quality of the screen just left so much to be desired.
the X was my first Android phone as well, and the moto blur interface didnt really click with me. the camera was also, at least in my mind not that good, pictures looked bleh.... could be a combo of the screen as well btw.
My Friend showed me his Vibrant and i loved the way it looked and felt, Yes its a lot lighter, almost toyish. but i found that the cover gave it the right weight and felt for me. so i took the X back and Got the Fascinate.
I know some ppl just hate TW. but i like it, i dont use it all the time, but i think for someone just starting to learn android its a great way to start.
