Not quite irrelevant. The specs were on a par with the other things that were out when I got mine because they'd been very ambitious.
In terms of relevancy of course, the specs aren't all that it's about, having proper gaming controls and a qwerty keyboard in such a small device means that it's an entirely different kind of thing to almost everything else that's out there, and that's still the case. It's hard to overstate how important good controls are to the enjoyment of playing games. I certainly missed my train stop playing Speedball II (emulating the Amiga) and ended up miles away from home...
