HTC ChaCha

If you're aged 14-21 and are after a fun mobile rather than a black slab of raw processing power, we reckon you'll find it hard not to like (or +1, if you prefer) the new 'Facebook phone'.
As the nickname suggests, Mark Zuckerberg's blue-hued brand of social media is at the heart of the experience – HTC even going as far as to give the site its own dedicated button beneath the ChaCha's decent QWERTY keyboard.
Break through the wall of modified HTC Sense and you'll note that Android Gingerbread is powering the experience, which should be welcome for the tech-savvy target audience. Less warmly received will be the Flash integration, which is a bit iffy to say the least.
With a funny shape and small screen to boot, you're really going to have to want the ChaCha's style of social oh la la to buy into this. Still, if you do, then this is something to post home about.
