Hello, I'm a PC user, I last used a Mac about 14 years ago in school! I am wanting to buy a new laptop and am interested in considering a powerbook G4. Needless to say, I am a little concerned about the compatibility of the Mac compared to a PC. I understand the Mac needs Mac-specific versions of software, but in terms of hardware like a USB mouse, memory sticks, etc....can you pretty much plug anything into a Mac that you can plug into a PC? And is it easy enough to connect a Mac to a PC network? I'd want to use the wirless card in the powerbook to do this - is this a problem? As you can see - in the words of Manuel from Faulty Towers: "I know nothing!" and any help would be very grateful!
