Smaller, faster, better, that's the way of the world when it comes to Semiconductors and Consumer Electronics. The Inq has a bit of detail on a Wireless client that fits in the palm of your hand.
"ISRAELI COMPANY Compulab recently announced a computer that manages to cram a complete PDA into a device two-thirds the size of a credit card.
The CM-X270L measures just 4.4 x 6.6 cm. In comparison, a MiniPCI wireless card is 6.0 x 4.4 cm - just half a centimetre thinner.
In this space, the CM-X270L somehow manages fits in an Intel (should that be Marvell?) XScale chip running Windows CE or Linux, half a gig of flash, 128MB of RAM, AC'97 sound and a Philips 802.11b wireless interface, as well as some things you wouldn't find on a PDA, such as a PCI bus, 4 USB host ports and wired networking."
