ok, i've only owned macs. i have a macbook with os 10.4 that i don't use. but i now want to run a program which is only available for windows. should i upgrade to 10.5/10.6 so i can run bootcamp or should i just get a laptop running windows. keep in mind i don't use the macbook at all right now. i could sell it and get another laptop. also, i have 10.5 on my imac, is it possible to use the startup disc for it to install it on the macbook? thanks for any advise......
