Read a book on all the Windows 8 secret functions... Suddenly it becomes an interesting OS. MS shouldn't have to force everyone to get a more bloated OS, because most people just don't need to upgrade.
The problem is that you are forced to have it pre-installed on a new system.
If you want to downgrade I am pretty sure the Win8 serials work for Win7. Dig around for a link from MSDN.
The mobile market sickens me. There is no innovation there. Just bigger, faster etc. to sell more devices.
Problems like: Your battery will last two hours in use, but then the competing model will have the same problem.
