SuN never claimed any problems with Win7, only supposed potential problems if it is removed. Since he does not want to run Win7 anyways, and is paranoid that deleting it could cause some sort of issue (which it would not), the best solution is to install a second OS, shrink Win7's partition to as small a size as possible, then simply let it sit until he grows the balls to actually delete it.
But you should really try some alternative OS's before ragging on Windows. Start with Ubuntu and see how long you can stand it. It sucks at least as much and often more than Win7. Linux, IMO, still just does not cut it as a desktop OS.
Perhaps you would like OSX more, but unless your computer is just right you will very likely have to jump through some incredible hoops to get it to install and run reasonably on an arbitrary x86 computer.
