Android is a flash in the pan, just like its parent OS, Linux. If you haven't noticed, Linux is an irrelevant flop for end-users.
It is doomed to Balkanization. There will be Motorola Android, HTC Android, Dell Android, etc. And they will all lock-in their customers.
Android is not a tablet OS, and Google shows its internal confusion by promoting Chrome OS for that role.
The Android market will become clogged by masses of horrible, buggy and insecure apps....
