I like to downloading from ITunes to IPods for my family and friends. What PC will give me the ability to do so, the fastest to multiple IPods on separate sessions at the same time? In conjunction, what is the fastest connection I can get for my home to ensure the fastest downloading? Fastest wireless network if using a laptop away from WiFi?

Any PC will do it. What's more impirtant than your PC is your Internet connection. The only PC requirement is a large hard drive to store the content.

Cable is generally the faster connection, but things vary depending on your location. Best to contact the carriers in your area.

The new Pre-N routers are the fastest.
