Four years ago, Asus introduced what it claimed was the world's thinnest PDA, the MyPal A620. The company has just launched the device's successor in all but name: the A626, an "exceptionally thin" model with Wi-Fi wireless connectivity.

The A620 still has the edge on thickness: it was just 1.3cm front-to-back, compared to the A626's 1.6cm. The A620 was later joined by the A620BT, a version with Bluetooth on board. The A626 has Bluetooth too - version 2.0, to be precise. The WLAN link is 802.11b/g.

The A626 sports a 3.5in, 240 x 320 display surrounded by a stainless steel shell. Inside sits a 312MHz Marvell XScale processor, 128MB of RAM and 64MB of RAM. It runs Windows Mobile 5. There's no word when it'll go on sale.
