Yeah, that would be a really slick little computer. A 1010 with a 2500-3000MHz computer inside it. :-)
If you wanted to be even fancier, and you aren't scared to cut your 1010 case a bit, you could mount a notebook floppy drive in there with the motherboard underneath it and have a complete system all in one small case. You can also get small (dimensional) powersupplies in the 80-120 watt range that would possibly fit into the case as well. When you think about it, a "giant" notebook motherboard runs off 6 tiny batteries for up to 3 or 4 hours. So it's not at all surprising that you can get a 2GHz-3GHz motherboard that requires such small wattage and uses little power. But then that's the nature of portable electronics.
I think it (putting a whole computer into a 1010) is a great idea, but then I like to tinker and build stuff.
