10.5 - worth putting on an iBook g4?

Hey all.

Fisrt post here woooo. I Have used macs before for a fair while and always prefered them. But I started work for a Microsoft Partner and that kinda put an end to that for a while. Now I've kinda caught up with Windows Im going back to the better way! got my OS X 10.5 exam booked in a few months and basically I am wondering if its whether it is worth while putting it on my iBook. Or sod it and get either a new macmini or macbook.

any one have any suggestions?

its a 14" ibook G4 (1.4ghz with about 1gb ram)

cheers

if you can up the ram, i'm sure that leopard would run great on that machine.

aw heck I've got Leopard on a eMac 1.25Ghz and 1Gb RAM, runs quite well...
