Toshiba's Folio 100 Android tablet has supposedly been pulled from the shelves of retailer PC World, after high return rates from disappointed buyers. Engadget found an overpriced demo unit at their local store - the £999.99 figure is apparently meant to deter the stores from putting out stock and demo units, as some sort of internal shorthand, though it obviously didn't work this time - and had a play with what's described as "a letdown" of a tablet. Low pixel density, poor screen viewing angles and cheap plastics don't help, and that's before you get to the missing Android Market and bugs in pinch-zooming and other aspects. All things we put down to pre-production status in the Folio 100 we tried back at IFA 2010, but it seems Toshiba hasn't ironed out those bugs. We're waiting to hear back from all involved with the official word.
