The responses are all over the place, from the old ][e (technically my first computer ever at school, though the first one I actually owned at home was a Tandy Color Computer my Dad bought from one of his coworkers) and //c up to the old iMacs and even a few people who can only claim iPod as the first Apple product they used. The first Mac I actually owned was much later than my first steps into BASIC -- when I needed a laptop a few years ago, I picked up a 12" Powerbook G4 and have been straight OS X ever since.
It's great to read this stuff, because you can see just how Apple has shaped people's lives. I was amazed to hear all of the emotion in the calls to Steve on our talkcast last week, but looking at something like this Twitter feed (to put your own memories in, just mark a tweet with the #firstmac tag somewhere in there) really shows you how dedicated Apple's products have made the company's customers. These people have all bought a Mac, whether it was a Mac SE (errrr, a Mac Classic?) or a MacBook Air, and never looked back since. Very cool.
And while we're at it, is it possible that you're on Twitter and haven't yet started following us? If not, jump in and do so now!
