the last mac i used as a user was an IIe
i actually tried offering support to someone with OSX on a lapshade mac, the person had little know how of computers, then i was trying to troubleshoot it... i couldn't even figure out how to open the cd tray on my own
right clicks really confused me at first was the no right button on the mouse!
i would reccommend listing the stuff you would like to do on a computer... video editing, publishing, surfing, daily tasks.. then see what programs are there for each side... because be aware, theres alot of programs that only work on one or another... narrow it down to "do i want to use premiere pro or ivideo? can i live without this windows only app?" also if you use other computers at other locations, besure everything can transfer, like files your working on
and i'm just going to go alongwith what everyone else is saying... you MUST use one to see for yourself before buying... find someone who owns one and see if you can sit down on it for afew hours
