My software update thing just told popped up with the security update and to my surprise the Powerbook graphics update, both pre-checked. The problem being it's only supposed to be for the 1.67 PBs and I have a 1.5. So should I install it, ignore it, or investigate further into the obvious (yet impossible) option of me in fact having a better computer than I thought? So is this not a surprise that it came up? Does it come up for all PB owners?
