Sharp has announced that the Galapagos ebook-based tablet will go on sale in Japan on 10 December.

The tablet will be available in two sizes and run via Android (version unconfirmed, although we've heard conflicting reports mentioning 2.1 or 2.2), although it sits more in line with traditional ebook readers.

First up is a mobile 5.5-inch LCD device, that has a 1024 x 600 resolution and has a track-ball for turning pages. It comes in two colours: silver or red. 

The bigger, 10.8-inch, HD (1366 x 800) LCD screen version supports a two-page, magazine spread format and is available only in black. 

Both devices are XMDF compatible and have 802.11b/g Wi-Fi on board. They feature “Automatic Scheduled Delivery Service” for periodical publications - meaning you can get your favourite newspapers or magazines auto-downloaded if you pay the relevant fees. 

They come with a web browser and social networking apps pre-installed and "PC data", which means that docs and maps can be converted to XMDF format and viewed on the device.

The 5.5-incher is priced up at 39,800 yen (about £303) and the 10.8-inch one will cost 54,800 yen (£417). As mentioned, both are set to hit Japanese stores on 10 December, and we've still heard nothing official regarding a UK launch.
