Thinking about how old I was when you were in 5th/6th makes feel old. Thanks for phrasing it that way. Oh and the supercomputer on a chip still impresses me.
Hey, I'm here to help! It's okay, at least with me, because I always feel old when I hear people talk about OS9, and I remember receiving it for christmas when it was new, and I remember knowing all the little tricks about it, and which pieces of software worked the best, and what combination of apps worked best, and what order to launch 'em in. And I've been called Grandpa in the IRC channel as a result of it.
I've also got a few other machines I once drooled over, things like the Pismo, the b/w G3, and heck, I remember days before i got the PowrBook G4, drooling about the newly released eMac G4, thinking it would be a great long-lasting type of computer. [

And that was in like 8th or 9th grade. I'd printed out the specs to the eMac at home and brought 'em in. I remember planning on which of my teachers I was going to ask to buy the eMac for me, as soon as I saved up the money. What memories.
As far as supercomputer on a chip goes... the hilarity ensues when you try to run Leopard on some of the older G4s. we've got a digiAudio/466 at the high school, with only 256mb of memory, and we managed to clone one of our G5's installs of Leopard onto it. It boots and runs apps, but it's
hilariously slow. Even our iMac G4/800s (15") with 512mb of ram are not too much better.
(regarding the IIc/IIgs comment) It's also funny how when we own something, we tend to want something higher end. My current computer is a Core2 iMac/2.16, and for whatever reason, despite the fact that this machine really is fast enough, I'd love nothing more than to upgrade to a Mac Pro.
