Title: Watch out for USB driver problems and kernel panics
Review: Six months into using OS -X started having Kernel panics (Apple's blue secreen of death). Not running non-Apple programs, multi-tasking, or running peculiar non-standard hardware (Logitech tracball, HP printer/scanner). 5 trips to the repair shop - new hard drive, new RAM, new system board, upgrade to 10.2.8; 4 phone calls to Apple "Support." Kernel panics returned. Lots of web searches - found lots of boards where people have the same experience, and found the only permanent solution was downgrading to OS9 or upgrading to OS 10.3. "Support" denies it's poor USB software.
