Are you planning to keep the device for a long period of time?
Take a look at the sales numbers... wm is on the downswing, Android sales are skyrocketing!
Also, Google continues to rapidly release new OS updates... since the launch of the G1, the 1st Android phone, they've gone from OS 1 to OS 1.5 to OS 1.6 to OS 2.0, all within a matter of just over a year! (G1 launched Oct. '08)
All OS updates are OTA (over the air), and free.
The Droid offers an amazing screen, excellent and fast processor and a decent keyboard. Those complaining about the keyboard don't mention that the keyboard is included, with almost NO sacrafice in overall size of the device... the Droid is 6 HUNDRETHS of an inch thicker then the iPhone, so it isn't exactly like you're having to carry around a brick (see HTC G1, for example) in order to have a fully useable keyboard (and yes, the keyboard, with a little practice and getting accustomed, is not bad at all) to gain the advantage of the physical keyboard.
One last thing... TONS of FREE apps in the Android Market. Yes, the iPhone has tons MORE apps then the Android right now, but having used my sons iPod Touch, and knowing the Apple market from his device, I can tell you that 1. almost any app you really need (replacement calculator, note pad, weather app, currency calculator, etc. etc.), you can find 3 or 4 of them in the Android market, 2. they're probably free, while the equivalent app on other platforms will cost additional money, 3. the market it going to really explode, with the addition of Verizon and Sprint being added to carriers carryinig Android phones, along with T Mobile.
