@Droid Motorola,
The hardest thing so far for me to get used to has been the fact that there is no dedicated row for numbers (like on my LG Env) The spacebar being in the middle throws me a little too, I end up hitting Alt instead of space a lot.
It's also taken some getting used to using a slider, I find T Y and U irritating to reach, especially with the body glove (I'm used to my thumb over hanging the buttons a little) I definitely type a lot slower on this then I did my Env. But I am sure after some time I will be back up to speed.
