Apple will probably have to because 9.1 is not compatible w/ the classic layer of os X. If I upgrade to 9.1 on my 1st edition graphite iBook, then I cant upgrade to os X unless I reinstall 9.0.4, which is a big inconvinence. if they release 9.2, or 9.5 or something like that that IS compatible w/ the classic layer, it would help alot. It was kinda stupid for them to release an update that wasn't compatible with the new os X.
