The Droid R2D2 and the Droid 2 are almost exactly the same except for the looks. The Droid 2 global has global features which gives you coverage if you travel a lot.
droid x, no its awful
It depends on what you want to do. The Droid X is slightly faster and has a better camera while the Droid 2 has the physical keyboard. In my opinion the Droid X is better.
not the droid 2
The droid 2 is a great phone. There are others out there, such as the droid X, that are a bit better but you will have to make that decision based on personal preference. The Droid X is rather large, and the droid 2 is smaller and lighter.
No, the two are quite different. The droid R2D2, is a fictional astromech droid used in the Starwars series. The Droid 2 on the other hand is a smart phone developed by Motorola.
Both phones are really nice 3G Verizon Droid phones. The Droid X2 is newer than the Droid Incredible 2, and in my opinion a little nicer. However, it might depend on if you like Motorola or HTC better. HTC makes the Incredible 2 and Motorola the Droid X2.
Yes, the Droid 2 has a video camera that shoots at 480p resolution.
yes of course it works
From my own experience, the main difference between the Motorola Droid 3 and Motorola Droid 2 is merely physical - - the Motorola Droid 3 is thinner than the previous versions.
DROID is actually a brand name which Verizon licensed to use for its Android phones. Many people actually use the Droid name to refer to any Android device (similar to the way that people refer to flying discs as Frisbees or clear tape as Scotch tape). The Droid Incredible is made by HTC and is a popular phone, but it is 2010 technology with 1 camera. HTC Incredible 2 came out in 2011 with a front facing camera and some other features.
the droid Eris is 99$ from Verizon with a 2 year contract.
