Laptops of all sorts are getting thinner, even the decidedly stoic and business-minded ThinkPad series. Hot on the heels of impressing us with its T400 refresh Lenovo is letting slip that it's having thoughts of putting its T500 series on a diet as well, with marketing manager David Critchley indicating that the company wouldn't be opposed to making a super-thin OLED version of the laptop -- "if demand is there." That's not really saying much since just about any company would do the same if they thought they could sell enough of the things. Well, maybe not Toshiba. That might be a little too exciting to fit in with the rest of its lineup.
