I know it's only 14" and a fancy screen protector but it's good quality, affordable, and from a popular and usually pricey brand. Hope it's of use to someone - especially with the surge in popularity on smaller laptops and the netbooks.
This was originally posted when £5.49 with free P&P but it's now £3.99. (Next cheapest I can quickly find elsewhere is £9.79 on ComputerWarehouse. Crumpler website lists it for approx. £16.24.)
"Its time to give it to them the Slip. They all want to get their mitts on one. So shiny, bendy and forbidden. But use your sliver shield to ward off all those sticky perpetrators. Its the wipe clean e-blanket for looking dynamite. Isn't it time you slipped one on?
More versatile than a transformer. Made from 100% Slippertex microfibre, that slides in-between your screen and keypad to protect from itching. It cleans your screen and if you're hard up its also a mouse pad."
