Have you heard about eeevolution? No? Then you are missing out big time. The little DVD box sized machine that pretty much does everything that your average HP/Dell/Sony spiffy new laptop does but at a fraction o weight and cost. It is a marvel, not to be missed out. It is XO for the rest of us (or for those who want a more expandable hardware).
I've had mine for a few days now. I never regret $500 I paid for this little bastard. Sure, its keyboard is cramped and Xandros is not my favorite Linux distro. Sure, it warms quite a bit and I sort of thought it may run longer on the battery it has. And certainly it'd be nice to also have a GPS, a Bluetooth adapter and an 802.11n wifi adapter in it. But even with the current spec it's great for the road, for a subway, for a couch.
