I loaded Linux distributions on both of my computers and never looked back. I'm not a Microsoft hater or anything but linux works great for my situation. It's free, does not require hardware upgrades for older machines, easy to use and opens most Word (.doc) and Excel (.xls) files nicely when using open office.
That's all well and good, but this is a thread about Windows 7. If you want to talk about your particular Linux distribution, feel free to start a thread and do so.
