Your iOS knowledge is dated. I can buy an app in iTunes and whe I pick up any of my devices it will be there. No syncing. I can buy an app on my iPhone and it ison my iPad. I can buy an app on my iPad it is on m iPhone. No wires. No syncing. iTunes is only required if I want to buy the App on my desktop.
This is not an iOS5 feature. It started about 6 weeks ago when cloud was announced.
On a largely unrelated note, the kindle has supported precisely what the android market does since the day it was released.
Your claim sounds a bit like one of the absurd in a web browser patents.
Ok - so 6 weeks is awhile. I'm glad we got THAT straightened out.
Any idea how long Android has been doing OTA?
