My daughter is very happy with her new 12" iBook. Everything is working perfectly, and hooking up printers and transferring files from her PC etc has gone very smoothly. I want to make sure that things continue like this So what utilities do you guys recommend to keep her lap-top ship shape? I'm only aware of a few - Disc Warrior, TechTool, Norton etc. Which is the best of the bunch in keeping all those bugs and crashes at bay? Second question. Anybody have any particular recommendations for a carrying case/backpack for it? You guys always gave me great advice before, so I'm looking forward to your recommendations. TIA Gary.
