Hi - New to this forum but here goes..
Try going to http://distrowatch.com/ look around a bit - on the right panel you'll see a list of popular Linux flavors. Near the top - you'll see a distro called PCLINUXOS. Of course try a few of them - easily download the iso and burn a "live" CD which you can boot from and try out that distro.
We use PCLINUXOS which we believe to be one of the best out there - It installs easily on just about any hardware - it's very customizable - it includes every linux program any of the other distros have and they can be installed through its package manager Synaptic.
I've been watching this distro grow for 2 years - I actually installed it a a few friends and some relatives PC/Laptops. They still use it !! they do everything they did on a Windows machine - hook up IPods - watch movies - play music - etc etc.
Hope this helps.
