I just replaced my Motorola Q9m with the Moto Droid this past Friday. I have been following the development of Android and anxiously awaiting an android handset on Verizon for over a year. Have been using WinMo smartphones for over 4 years (XV 6700, then the Q9m). So far the Droid is FAR superior to the WinMo devices I have used.
One of the greatest things about an open system like android is the great developer community and wide availability of free apps. I have downloaded over 30 apps already and only paid for one (Beautiful Widgets - well worth the $1.50).
Can't wait to discover even more good stuff that my Droid can do!
