In the evening I like to use my Linx in the dark, and am use to having an illuminated keyboard on my Dell XPS13. To do this I came across a Kensington Backlit Keyboard (part no K97087UK). Although intended as an Ipad keyboard it seems to work fine paired to the Linx.
The keyboard has a groove in which the tablet is supposed to rest in. I found the Linx to lie almost vertically in it and to be not very stable. A better solution was to put the Linx in a case I get off Ebay and put the edge of the cover into the groove
I bought this from an Amazon Marketplace Seller UK Surplus Central Ltd few days ago for £24 delivered, though they have just increased this to £30. They also sell on ebay for the same price.
