From a manufacturer standpoint, 4G (for the purposes of this post I mean LTE and WiMax, not 3G+) is a bit of a nightmare. The immaturity of the technology means that chips are expensive and bulky, and realistically offer benefit to only a small portion of consumers. (Compounding the issue, "4G" has become yet another buzzword that consumers don't understand but think they need anyway... but I digress.)
Consider a diminutive device such as the Samsung Galaxy S II. It's thin and light, but could a 4G chip be integrated without expanding the dimensions in one or more directions?
