Overall my preference is the Windows systems for several reasons.
1. You can get more software titles with Windows than with Apple. That includes games and business software.
2. You have more upgrade options with Intel based systems. (For those of us that like to tinker that is a big deal. All three of the systems at my house are home built.)
3. Saturation. Windows based systems sit on more desktops than Mac's. Windows users are comfortable with them.
4. The Cube. The biggest disappointment I have ever seen/bought/used. I swear I can walk within 20 feet of a cube and it will crash. (Must be all that Wintell Karma freaking with the Mac Mojo.) Had one in my office that would cycle itself on and off damn near every time I breathed.
5. The Colors. Spray Paint is cheaper. I mean If I want my pc blueberry blue I can spend $1.19 on a can of spray paint rather than spend an extra $500.00 for the luxury of color.... and the PC's skin can take it.
6. Any moron can run a system of Mac's. That would put this moron with way too much training out of a job. That's a bad thing. :)
Nothing at all against Apple. When I can; purchase equipment for the same price as I can for my pc, or I can use the same case to upgrade motherboards, processors etc..., put any video card in, purchase any game or productivity software I want... When I can do all of that I might just buy an Apple. But by then would it really be an Apple?
