There's a funny thing taking place in the mobile phone market. The first portable handsets were big and bulky, and the race was on to deliver smaller, slimmer phones. Then mobile phones got smart with touchscreens, dual-core processors, full-fled operating systems, and all sorts of advanced features, and now the trend is towards bigger devices, culminating in handsets like Samsung's Galaxy Note and, as teased to the Web, LG's Optimus Vu.
