So tired, so very tired of explaining it all...
IBM compatibles were some of the choices when I went to buy a new computer. So was Apple's DP 1.8 G5.
But after spending my work days on an HP and dealing with XP and it's quirks and watching my family and their shiny Dell's go through the virus and spyware shuffle, I went with Apple.
And to keep at least slightly OT, there aren't a lot of "more choices and cheaper prices" music stores (including Real) that also WORK AS WELL as iTunes and are compatible with OS X.
