That's what I do, but not due to any choice on my part. I love my new laptop, except for the fact it crashes randomly. Because of this I have become recently acquainted with the windows debugger. It make deciphering crashdumps easy, so you can find out what drivers are causing bluescreens. Or you can buy a mac, ha.
It's a sad state though, how little help one can get from the manufacturer. I called them, because I wanted it on the record that I was having problems for warranty reasons, and there answer was to defrag, and if that doesn't work, reformat. Oh, while I was defragging my brand new hard drive, they went ahead and closed my service ticket. We expect crappy service, and that's what we get.
Anyway, it's pointing to a driver conflict with the kerio firewall I was using. So I uninstalled and am temporarily using the Windows Firewall. Whatever works.
I'm putting ubuntu on my other laptop. I have waited too long to get my feet wet. Now I can leave comments on slashdot and not feel like a fraudster.
