Well, for those options, it mentions that it can accept LAN cards on CF, and I've heard of HSDPA and EVDO CF cards (obtainable with data plan from providers, I think) in passing, though owning no devices taking that form-factor, I've paid little attention. Probably no WiMAX yet, though.

I'd rather full Ubuntu, or maybe Debian, than mobile, but if they've got drivers for one, I bet the others would be easy to put on. With vista, it's unlikely you can get even XP working with full hardware support, much less a decent UNIX. (I have yet to even try Cygwin on Vista, but from the performance on my laptop, I can't imagine Vista being workable in these hardware constraints with or without a UNIX layer.)

Does it support USB? The EEe does. There are 3G USB options available.

OK, I'm gonna rip a couple shots from the manual here, but yes, it's got USB (qty. 1 on the unit, +4 on the port replicator). No, I don't think there's room for all the internal USB hacks people do on the Eee (though electrically, there's at least one more USB, on the port replicator connector), and no, I don't want a dongle hanging out the side of it all the time; I'd definitely hope CF are available.

(One other point of concern, were I rich enough to buy this, would be the SD slot; my current laptop leaves SDs sticking half-way out, probably to support RS-MMC, but that makes it implausible to keep an SD in it all the time. Then again, I've got such a big HD that another 16 GB of always-on storage space is not all that helpful. This probably doesn't, so I hope it's not like that.)

Jeebus... $1300?! I'm thinking ~$750 is probably my personal top end price point for a UMPC type computer.
