I haven't bought the Macbook yet (waiting until after WWDC) but I was looking at some tutorials on the Apple website and saw that in order for me to get the WiFi connection with my MB, I need the Apple Airport base station. I already have a Linksys router, is that enough to get internet connection with my Mac? Since I've been a PC user for years and just recently decided to buy a Mac, I wanted to buy an external hard drive to put all my music files and pictures and such from my PC and transfer them to my Mac. Do I need a specific external hard drive or do they work for both? Thank you.
