yea i am contemplating doing the same thing on my laptop, lol, never used linux before but its gotta be an improvement.
If you have a free 4gb+ Usb stick around it costs you nothing to boot a live distro off it to check it out. No need to commit instantly. If you boot of a USB and everything just works it should give you a good idea what your looking at if you decide to install it to a hdd.
