'I mean seriously, how am I going to use it?'
'With a keyboard' is the simple answer. But I expect you meant something more along the lines of 'What use would I have for it?' And the best answer for that is, If you have to ask that question, it seems likely to me that you won't.
It's for those of us that are the sorts of geeks that don't need to ask that question. Not everything is for every one. If you have no use for something, then don't worry about it. Just move along and let the rest of us worry about what we will do with it. Personally, I plan to try it out for fixing systems for by getting around an OS that has the hubris to tell the owner what they are and are not allowed to do on a system they own. I'll also likely fire up some of my old games as well, though I'll likely need to dig up a copy of 'moslow' to slow the system for the games that ran off of clock ticks rather then actual times. Heh, Stellar 7 on a 286 16 mzh was playable... But even the slowest 386 and the game was over before you could twitch.
The better question, and the one most folks look to be answering is 'How are you going to use it?'. From the looks of the replies the short answer to that looks to be 'Any way we can think of'.
