BLU Studio 5.3 and Touch Book 7.0 hands-on

You know handset vendors like Samsung, LG, HTC and Motorola. You've probably even heard that manufacturers such as Pantech, Sharp and Acer produce phones as well. But have you ever heard of BLU? If you haven't, don't worry -- you'd be in the ranks of the 99 percent. Calling itself the "leader of the Latin America market with vision to expand worldwide," the outfit is nothing if not confident about its stature in developing countries. In the US, however, it's a completely different story: here, BLU is a virtual unknown: a low-profile brand, selling unlocked phones and tablets via e-tailers at bargain-basement prices.
