…whether I should upgrade my PowerBook G4 (12″, 1GHz) to Mac OS X Leopard 10.5. I currently have the original 40GB HDD installed, so perhaps I should upgrade that first (given Leopard requires 9GB to install). The G3s I have will all stay at 10.4 for the time being. They are all sub-500MHz so I don’t think any amount of hacking will make 10.5 worthwhile on them.

For the record, I don’t think Apple making the minimum processor required for Leopard to be an 867MHz G4 is unfair. And I have lots of old Macs that can run 10.4 🙂

Edit: I will probably wait for 10.5.1 to come out.
