I am getting an iMac G4 in a couple of weeks and I don't know if I should install Mac OS X Leopard (10.5.8) or Tiger (10.4.11). The Specs are: RAM: 1GB Hard Drive: 80GB CPU Speed: 1.25GHz Screen Size: 17 inch I will use it for Web Surfing making the occasional movie and photo album and that sort of stuff. Burning CD's and more. I don't want it to be sluggish. If leopard will be a little I may have to go with tiger. If so whats the advantages and disadvantages, excluding Time Machine and Spaces.
