i work for apple. if you want something to listen to music on and be able to browse and watch youtube videos get one, it's pretty sweet for that shite.
get a macbook to go with it though...lol
Once you go Mac you never go back! LOL My house is starting to have little Apple Logos all over the place ...
Seriously, I have used iPods with both PC & Mac. It is 10x easier to use with a Mac.
Another cool feature with the iPhone & iPod touch is the video feature. With the use of a program called Handbrake you can download a DVD to your computer and then sync to your iPhone or iPod. Quality is amazing.
