A little junk in the mobile trunk never hurt nobody, but don't tell that to Fujitsu, where thin is clearly in. The company's gone all out on its latest handset -- the Arrows ES IS12F -- for Japanese carrier KDDI, hitting marks for both svelteness and ruggedness: pairing a 6.7mm profile with a Gorilla Glass and scratch-resistant body coating (think: the Brawny Man as a phone covered in Teflon on a Master Cleanse). This 4-incher's outfitted with an 800 x 480 AMOLED display, single-core 1.4GHz Qualcomm MSM8655 processor running Android 2.3, 5.11 megapixel rear shooter and, in keeping with the Arrows tradition, it's also waterproof. If you're living in the Land of the Rising Sun, you can snag this slight smartphone in Ruby Red and Gloss Black starting January 7th. Sorry, chubby phone chasers, you're gonna have to sit this one out.
