Calling Android a rip-off of Windows Mobile is hilarious. If Windows Mobile were one tenth as good as Android, I doubt anyone would be considering non-Microsoft smartphones. But the fact of the matter is that Windows Mobile is a nightmare to use and a nightmare to program for -- and is very, very outdated.

Android may be a rip off of iPhone OS, but it's certainly not a rip off of Windows Mobile.

(I could barely even make calls on my Windows Mobile phone, much less browse the Internet in a meaningful way. On Android, those two things both work wonderfully.)
