Mint's popular. Avlinux is good. I really cant recommend centos.
The one remaining hardware issue area with linux is webcams. Use a driverless (is it UVC?) webcam and youre on safe ground. Such kit is extremely cheap.
Try what you fancy by booting from the dvd, it runs live. Its slow that way, but you get to check youre ok with it before installing.
Linuxes generally have some big upsides. Pick one with every app you want already installed, as adding apps later doesnt seem to go as smoothly or easily as with windows. Desktop linuxes generally come with everything you want and far more already setup.
