The apple store has the entire product range from the the new iPhone 3GS, iPod classic, iPod Touch, iPod Nano, MacBook, MacBookPro, MacPro, iMac, Mac Mini and the new apple TV.
Good points: They have very high quality products.
Bad points: Very expensive.
Overall: Whenever I'm looking for a music or computer related product I always check out this site. They're very reliable and have top notch quality products. They're pretty expensive though and you can probably find their products being sold almost anywhere else for just a little bit cheaper, but then you lose that reliability, warranty, and great customer service.
