I would like to put tiger on my powerbook, but I dont have the time to do it if I'm going to have to deal with heat issues, etc. From looking at the posts, it seems all of these are on 1.33, etc older machines. I have a new model (1.5, but newest rev) so will it probably be just fine if I archive and install? Would doing a full reformat install be functionally better in any way, as in cleaner, run better, etc? Thanks!
