I still have my 1989 motherboard-- 386, 1 megabyte of RAM, 80MB hard drive... I remember booting it up for the first time and DOS reporting only 640K of memory and calling them up to wonder where the rest of it went. They were very nice about explaining it to me over the phone.
(...hah, I still have the letter confirming my order. "We welcome you as a Gateway 2000 customer and have a good day!" Nostalgia2k for the cow boxes!)
I've found it's a nice little ritual to start and end the day-- get into work, turn on the keyboard; go home, turn it off. My one complaint is that the black paint on the home keys started to wear off about five months after I got it; now, a little over a year later, the S/D/K/L keys are very smudged. I wrote to ask about it and their response was basically "Yeah, that happens." They offered to replace them (within the first year), but I figured they'd just wear through again. (Maybe I have unusually corrosive fingertips?)
