Acer Liquid E1/Z2
Acer is unveiling a whole new lineup of smartphones in Barcelona, and at the top of the list is the Liquid E1. The Android device comes with a 4.5-inch HD display and a dual-core 1GHz processor, plus optional dual SIM cards and a dual speaker system with DTS Sound. The Liquid Z2, meanwhile, is Acer's new entry-level smartphone that reportedly sports a single-core 1GHZ processor and a smaller, 3.5-inch display. The two phones will be available this quarter, but Acer hasn't revealed pricing or launch dates.
