Query: not for older macs

If your buying a new mac w/ leopard of if your computer is just a few months old then Leopard is awesome!!!But I upgraded on a 1.5 powerbook and it came to a screaming halt! I have never been so unhappy w/ my laptop. Put it this way my old 800 g4 iMac now runs circles around my powerbook. I don't know whether to reformat my powerbook or wait and hope for updates.
