Android is taking over the cell phone market. I see windows mobile becoming almost non-existent(hopefully, only phone I have owned that had Windows Mobile was a hog on battery and got slow a a snail in two weeks, went back to my palm)
The Droids like a fun phone, but like with any new phone release it will have problems. Just wait a month or two and find out what they are and if you will be able to deal with them until they are fixed.
