OK so i have never owned a Mac but will get an iMac shortly when the new ones are released. Anyways, excuse my ignorance and stupid questions, however with Time Machine on Leopard am i able to plug in any hard drive (via USB or Firewire) to the iMac's back ports and let Time Machine still work and use that hard drive as the back up hard drive? Also will it do so automatically? Second question, is there any other device like Time Capsule that will allow me to back up wireless? if not, is there any roundabouts way to get to back up wireless? Once again sorry for my dumb questions, I am a Mac virgin. I just hear so many bad things about TC but i just want a simple backup solution that will cause no trouble. I was thinking Time Machine on Leopard would still back up automatically and all in the background via any normal hard drive.
