I I was offered the upgrade for my new laptop by Samsung but I refused to go ahead and upgrade from Windows 7.
Windows 8 is very different from the currents OS's in terms of user interface, it works far better with a touch screen PC as many of its functions are easily accessable by swiping the screen. Windows 8 is geared towards folks who are entertainment/social freaks. It's more of a plaything rather than a working mans machine.
I happen to sell computers at my workplace and have tested all brands and types of computers be it laptops or desktops since October 26th. This was the main reason I was able to decide to stay away from it, atleast for now. We actually had more returns than ever before. The customers either were unable to use it properly or had issues with propriety software they were using which did not have support for Windows 8.
A lot of consumers these days are more interested in hooking up the computer with their large screen smart TV's, obviously the reason for that is the entertainment side of the new operating system, youtube, facebook, skype etc.
Google TV from LG is selling like hotcake these days, it does most everything a computer does on wifi, except it has no hard disk.
