I bought an Apple Performa 614 in college. This was because I was sick of going to the CS lab to do assignments. I wanted to program in my dorm room. Of course it took about 45 minutes to compile anything with only 8 megs of RAM, so I went to Fry's and bought a 16 MB stick, to bring me up to a total of 24 MB. No more thrashing, compiles took mere moments. That computer stayed with me through college and then I gave it to my brother so that he could use it in college, since it already had the software he needed. Even though the Performa line is looked upon now as the dark days of the Mac, I look back on it fondly. They might have been coasting on inertia then, but the foundation of quality that had been laid before carried through, at least in my mind.
I then defected from the Mac camp and bought parts to build my own Celeron 300, which I occasionally overclocked to a magnificent 500 MHz. Why did I defect? Well, mostly because I could cheaply put together a machine that had a 3D card. This would make it easier to improve my 3D asteroids game.
That computer is still running, but doesn't see much use. I get a new laptop from work every few years which has killed my need to buy a fancy machine of my own. Of course I occasionally have wanted to go back to the Mac camp, at least for personal use, but I never had a good excuse, and I while I've had the money to buy one if I wanted, I was never quite able to justify it.
Why am I writing this? Because I just ordered my third computer, a mini Mac. The price is too good to ignore, and I admit that the design impresses me. They lowered the price to the level of impulse buy and they hooked me. Now I just have to find a cheap 1 gig stick of RAM somewhere...
