My ThinkPad came with Windows and I never bothered removing it. However, it would have been nice to have been able to buy it without Windows, but thanks to Microsoft's legally proven strong arm tactics, that option is not available with most computer vendors. That ThinkPad, however, is the only computer I've ever owned that came with Windows installed. My computers have generally been "white box", where I could specify what I wanted or refurbs that came with no OS. On my own computers, I ran OS/2 for several years, before switching to Linux. I do have an Asus Eee PC, which I got from my bank, that came with Linux installed.
