I was forced to switch this last year. I decided to upgrade my 10 year old motherboard, and Windows refused to boot with the new one despite nothing else changing. I absolutely refuse to pay good money to "upgrade" to a worse version of Windows, so Linux it is.

Mostly it's been a good experience. I can still open all my old documents, and you can't even tell the difference when browsing. There are some Windows only apps that I relied on, including a couple I helped develop - I haven't figured out how to deal with the loss of those yet.
