i use both...forced to use pc at work...but prefer apple much more
it all depends on what you need out of a computer.
if you need to run a spreadsheet, type your resume, browse online then you can probably be better served with a cheaper pc.
if you need a computer to express your creative side, like audio, or like video and graphics, then mac is where it is at.
macs are specialized machines...while pc's are for the average...thats why so many companies build pc's and only apple makes macs
