I agree

Add in the 50 to 100 a year for anti virus software that you don't need on a Mac over the life of the machine and the time you spend reloading the windows osv over and over it really starts to add up.

Having a single hardware and OS platform has a lot of advantage's. If you had a single hardware platform with Windows it would go a long way towards a better TOC for a Windows machine. Maybe Microsoft will take a page out of apples book like Google is starting to do with its Android devices. Being highly integrated is a huge plus in my book. No bloat and much easier on support for hardware drivers etc.

Small is better!
