Like the 7100, the BlackBerry 7105 is slimmer than the typical BlackBerry with a compressed 20-key layout. It also suffers from some of the same drawbacks as the 7100: a meager 32MB of memory with no room for expansion and no EDGE support. BlackBerry 7100 fans will like the improved button layout and scratch-resistant screen, but true "CrackBerry" enthusiasts are holding out for the full-size Intel-powered BlackBerry 8700. 7105 review | 8700 details
