HA HA! I’m still running Tiger on my MacBook. Never had a real reason to upgrade except maybe for the annoying fact that Tiger can’t preview jpeg files as thumbnails (um, Windows was doing that eons ago)
I ‘ve got too many PCs at the moment. I only use the MacBook when I want to play with something fancy.
My brother says that macs are PC equivalent of a Range Rover. Strictly for Starbucks Yuppies! :-)
