Oh and ignore the itunes and apple people if you own a pc, they dont realize that you do not need that hunk of software jamming your system if you have Windows. Just download your tunes at Amazon.com, and burn using windows media player. Easy as pie.
I disagree. iTunes is only using about 15-20 megabytes of RAM on my system right now, while Firefox inevitably balloons to over 200 megabytes with every new instance.
I've used pretty much every popular media player/organizer out there since before MP3s (CD player app in the early 90s), and I settled on iTunes as the best long before I ever got a Mac.
