Touted as a competitor to Asus's Transformer Prime, the device comes with Android 4.0 Ice Cream Sandwich on board and a detachable keyboard cover.
The tablet measures in at 8mm, making it one of the most slender on the market. However, with the 5mm Coverboard attached it marginally exceeds the girth of Apple's iPad.
Archos's 101 XS is powered by a multi-core A9 processor running at 1.5GHz and 1GB of RAM, with 16GB of memory on board and a display resolution of 1280x800.
Support for microSD, USB 2.0, mini HDMI, Bluetooth, Wi-Fi and Wi-Fi Direct comes built-in, as does a front-facing 720p camera for HD video capture. The device's operating system will be upgraded to Android 4.1 Jelly Bean in November, TechRadar reports.
The Archos 101 XS will be released in mid-September, priced at £299. Both 9.7-inch and 8-inch models of the tablet are also in development.
