Short and sweet version.
I bought my dad a B&W G3 300 and it works like a charm, Runs Panther (so it never crashes) and gets him online so that's all he needs.
Now my Grandfather talks to me and he wants the same deal that my dad got.
Over at PowerMax.com they have one B&W G3 400, 768 MB RAM, etc.... but also three models of G4s that are actually CHEAPER than the G3.
In my older days constantly visiting LowEndMac I found that the B&W G3 got amazing reviews and is considered one of the best Macs ever made.
I dunno if it would be worth saving a hundred bucks and getting a Digital Audio G4 Dual 500 that may or may not sh!t the bed on him.
What would you do?
Here is the used Mac page at Powermax.
