I don't (it came bundled with my laptop, but it's been wiped off in favor of a real OS). You can build your own desktop, but with a laptop you're pretty much stuck paying the MS Tax, which a great many people find irksome (consider how much the hardware would cost if OEMs sold pure hardware). Furthermore, not buying the software does not change MS's anti-competitive tactics.
Not really. I bought this laptop abot 3 years ago without paying for Windows. The vendor was very good about allowing me to order it without any OS pre-installed.
It has never had MS on in (except in a VM), and it never will. And it'll be good for a while yet as it has a 3.2Ghz Desktop HT CPU, 1G RAM, a full-sized keyboard, and (at the moment) 80G HDD. I'm looking at adding a 120G HDD in the near future.
The point is that if you really don't want MS, you just need to shop around a little, and vendors who will work with you are fairly easy to find.
you can get any computer without windows preinstalled, if not then sue them..
