Sony Vaio pocket computer. Its a bit of a rare special item (originally only sold in Japan) so might not be familiar to many.
Its like a Netbook but more pocket-sized, slimmer, and widescreen.
Currently running Windows 8.1 but can always put 7 on if required.
Comes with spare battery and charger. One recently sold on Ebay for £190 (item 171607730465), but I don't like selling on Ebay.
£100 no offers.
