If you’ve ever toyed with Nokia’s N8, you’ll know how it feels: heavy. Like a cricket bat made of iron, shrunk for added density. So these drawings of an N8 design-inspired tablet should strike fear into anyone who likes featherweight gadgetry. Dug up at the US Patent Office, the year-old submission shows what Nokia was planning for its tablet debutante. Whether that design will survive into the Windows Phone 7 era remains to be seen. But if it does, be afraid… and get a bag with a padded shoulder strap.
