Japanese carrier KDDI au has now followed Softbank and NTT DoCoMo in pulling the red velvet cover off its summer 2009 devices, and as always, there are some neat tricks in here. From Toshiba, the Biblio is billed as an e-book reader; granted, it's using an LCD instead of an E-Ink display, but it's a doozy at 3.5 inches at 960 x 480. It features 7GB of user-accessible storage on board for books, and also has a slide-out dynamic keyboard that can display a numeric pad in the portrait orientation or full QWERTY in landscape. Moving on, the Sharp Sportio Water Beat -- as its name suggests -- is a waterproof sports-oriented set with advanced calorie and distance tracking (a la Nike+), but you're still never too far from your true destiny as a couch potato thanks to the phone's one-seg reception. Next, the Hitachi Mobile Hi-Vision Cam Wooo is the latest in the multimedia-centric Wooo series, becoming KDDI's first phone capable of 720p video recording at 30fps -- and there's HDMI-out on board for when the time comes to enjoy your footage. Finally, the SH002 is the realization of Sharp's solar phone concept from earlier this year, delivering one minute of talk time for every 10 minutes of charge time. There are other announcements in the mix here -- eight new phones in total -- but those were the killers of the bunch, and as always, this post is about as close as most North Americans will ever get to them.

Proving (as usual) that it's not too big for a little tit-for-tat with its crosstown rival, LG showed its own concept solar phone at MWC this week to match up with Samsung's Blue Earth. The prototype LG handset doesn't have a name -- takes a whole team of high-priced consultants to christen a product like that, we'd wager -- but we do know that the slider can eke 3 minutes' worth of life out of a 10-minute charge in natural light. The thing looks like it was thrown together in a week, but hey, as long as it works, we know LG can take care of the design side of things by the time production rolls around.

The entirety of civilization seems fairly well and dedicated to one-upping each other in the "green" department, and Samsung is looking to up the ante once again by stating that "blue is the new green" and putting out the new Blue Earth solar phone to prove it. Sadly, the Blue Earth isn't quite ready to go -- currently it's only to be seen in non-working mockup form, though the hardware is certainly looking good. Samsung's showing off its eco-packaging and built-in energy-saving functionality, including an "Eco Walk" function to let you know how many trees you save by walking places. The phone itself is built from castor bean extract and recycled plastic, and Samsung claims the integrated solar panel saves up to 34.6% of the battery's energy. They're also showing off a hand-crank generator, external solar chargers, and even a solar-charged stereo headset. It's clear that Samsung isn't just playing lip service to green (or blue, as the case may be) but at this point in time this technology is likely to act more as a gimmick and promise of things to come than a truly life-changing device.
