I've thought about getting one of these before, but the 1 unit backspace is something I hate so much. I'm just too lazy to mod the thing so I just use my XT. If Chryos ever manages to do that documentary about keyboards, I hope he gets to the bottom of the reason the 1 unit backspace even exists. I know we generally laud designers for their achievements in retrospect, forgetting or forgiving them for the bad things they came up with, but this deserves some explanation, especially considering how trend-setting IBM was at the time.
If anyone can find some explanation for this, I'd like to know about it. I understand there can be technical challenges, but even modders can put a 2 unit backspace on this thing. I want to believe there is a really good reason for this, because it's such an obviously bad design as far as pure usability goes.
