My logic board on my PowerBook is bad and my plan was to sell that for parts along with a few accessories and pick up a PowerMac G4 to use until I can buy something new (I have and ADC display). I have a local trade offer for a Digital Audio PowerMac with a 667mhz processor and 512mb RAM, which I would probably double. Would this work reasonably well with Tiger (possibly Leopard) for basic tasks? (web, email, iTunes, Word) Also, is the trade a decent one? I've been looking at G4's on ebay, but haven't seen any 667's, so I'm not really sure what they typically sell for. I would love the convenience of a trade, but I'd rather go through some trouble if this one won't quite meet my needs for the time being. Thanks for any advice...
