This is the last version of Windows I'll ever intentionally buy. I have one dedicated WinXP machine for legacy work, two Linux machines (one Mint, one multi-boot with Mint, PCLinuxOS, & Puppy), and my netbook which dual boots WinXP and Linux Mint. I briefly had a Vista laptop, but I gave it away to my granddaughter - good riddance!
I still maintain Windows machines (WinXP, Vista, & Win7) for others, so at any given moment, there's likely to be one or more Windows machines (along with other Linux machines) in my house. But, I'm done with them for my personal use.
Which version of Windows are you running on your main computer at home?
A version that is too embarrassing to mention.
I don't do Windows.
