I use the Suse version of Linux which co-habitates well with the Windows operating systems.

The SUSE did work great as dual-boot.
job, your Windows software won't run on Linux unless you use WINE.
There is a linux equivalent for alot of stuff, but if you are big into gaming forget it.
At this point linux is best as a desktop if you're just doing internet & office work.
