Well, my user name is actually an understatement. I have three computers in on or near my desk -- a work laptop (IBM ThinkPad T41p), a homebuilt AMD Sempron 2500+-based machine, and a homebuilt Intel dual core 2.8GHz-based machine. Then I have a server down the hall that's probably another AMD Sempron machine (not even sure), and downstairs is my wife's machine which is an Intel P4 2.4-GHz-based machine. These are all home-built machines all running Windows 2000 Professional. I also have two old laptops I don't even use in the closet, and I built computers for two of my three kids who live out of the house, which I also maintain for them.
So all in all that makes 9 computers that I own, 7 of which are running productively.
This doesn't count my Palm TX which is where I actually do all my email (Snapper Mail) and keeping track of money accounts (SplashMoney), as well as game playing and Web browsing. I've been known to order from woot.com off my Palm TX while lying in bed at 1 am, or to bid on something on eBay.
