I probably will not be purchasing the Droid X.
The Moto Droid has served me well for about 8 months now. With a new phone every 20 months I'm down to just about a year until the next phone. I seldom use the keyboard but it isn't in my way either. Too early to guess what I will pick up at that time. If the phone can be made to run whatever the latest OS version is I'll be happy. My guess is most newer phones will have better resolution, video out and who knows what else. I don't picture them having projectors and LED infrared keyboards just yet, but who knows.
