I have a copy of Jaguar, but I'm unable to update, due to the fact that Lexmark hasn't released drivers for their all-in-one X73. That's a totally different story. I was wondering, how much space does a standard upgrade take, and how much does an archive and install take? I've only got 1.38 GB avaliable. I could destroy things, but don't particullarly want too - as I don't have a Firewire HD Drive at the time. One other thing, should I avoid archive and install, as it makes new everything? Could this be a problem with application support, and Norton Systemworks 2.0? Don't flame me for the use of it, just try to answer me question please.
