Starting to get bored of the ThinkPad's classic look but not keen on the Edge series? Then we have good news for you! Earlier today we received a couple of photos that show off two upcoming Lenovo Ultrabooks: the 13-inch ThinkPad S3 (codename "Labatt") and the 15-inch ThinkPad S5 ("Guinness"). As you can see above and after the break, both aluminum laptops feature a new "floating design" that might have taken a page out of Samsung and Vizio's book: shaving off the front outer edges of the bottom side to create that slim and floating illusion. Also, these will apparently come with either a black or silver lid.
Some folks on Sina Weibo have received other teaser photos of the ThinkPad S5, with one confirming the presence of JBL stereo speakers. The funny thing is Chinese website Yesky reported on a charity auction that actually sold limited editions of the S3 and S5 earlier this month, but those unannounced Ultrabooks went under everyone else's radar. If you're curious, Yesky speculates that a launch is due in China at the end of this month, but you'll have to stay tuned for the prices and specs.
