i have a powerbook running os 10.2.8. it will be getting switched to 10.3.whatever to get my airport express configured and so forth. so that will happen soon. with that in mind, in this transition, should i expect to wipe the hard drive and start over? could i just update the os and leave the apps and email and such on the drive? if i should wipe the drive, is there an "easiest way" to retain my users settings so i can come back to them after the os update. thanks for any tips. ps: in the futures i'll get a big old ipod, perhaps a 60 gig one, and do the home on an ipod whatever it's called thing where i can back up the personal stuff that way. in the meantime i'll need to find a different way.
