If an ultra-portable laptop/tablet with a SIM card slot — yes, like those found normally in GSM mobile phones — makes your gadget dork fluff up a bit, you might want to check out this review of the Dialogue Flybook — the first English review I've seen. Besides being tiny, the best thing about the Flybook is its extra connectivity. Not only does it have the standard Wi-Fi and Bluetooth, but it also has GSM/GPRS capabilities (hence the SIM card) so that you can, in lieu of any other, faster connection, hop on your cellular carrier's GSM network and get internet wherever you are.

The Flybook technically isn't a handtop, but it's not too hefty, either, as you can see in the picture. It does look bigger than a DVD case, though — no matter what Handtops.com says.
