Welcome home Mac
I've just got one of my Macs back from repair. It had a power supply problem - we had a power cut or surge at about 2am a few weeks ago and something happened that the computer didn't like. Fortunately the local Apple service centre managed to fix it.
We had been using the computer as a hub in the house. Whilst I had thought of a back-up policy for the data what I hadn't realised were the problems that I would have if I lost lots of the ports. Most of my data was on a series of external drives (320Gb ones) linked by Firewire 800. Then there was the ipod, the iSight FW camera, the printer, scanner....... you get the picture.
My poor little Powerbook was bought because I thought I didn't need all of this stuff directly connected, I would just use it connected to the other computer and connect over the network. That presumed that I would have something with lots of ports available. In Apple terms that means a Power Mac. Without it I was lost.
It's back now so I can sigh a sigh of relief. Somebody once said that technology was there to make our lives easier. It might do but we do end up relying on it, and when it is not there we struggle.
