Microsoft will release Windows 8 this fall, putting PC users in a bind. Should you upgrade or stay where you are? That depends on your current version of Windows and how much you like (or dislike) Windows 8.

Windows 8 will be a departure from previous versions. Designed for tablets, specifically Microsoft's upcoming Surface, it sports a new interface that uses finger-swiping. But there is some question as to how this will work on desktops and laptops. Do we swipe or use keyboard and mouse? How functional will it be in everyday use, and how difficult will it be to make the switch? No more Start menu. No more taskbar at the bottom. If you visit Microsoft's Windows 8 site you'll see how different it looks.

There's also some question about how multitasking will work. Since Windows 8 is optimized for tablets, instead of many windows open at once, you can only have two. This is because of the way programs behave in the background in Windows 8.
