Another day, another tablet launch. Just a few months after announcing the 7-inch B1-720 Android tablet at CES, Acer has decided it can do better. The company just announced the Iconia One 7 (aka the B1-730), another 7-incher, this time with a sharper screen (1,280 x 800 resolution, up from 1,024 x 600). Just as important, perhaps, Acer went with a faster Intel Atom Z2560, which should be an improvement over the bargain-basement MediaTek CPU used in the last edition. Not just faster, mind you, but perhaps more energy-efficient, too: Battery life is now rated at a more respectable seven hours, whereas before it could only last five. As for software, Acer says it will ship with Android 4.2 (Jelly Bean), but will be upgradeable to Android 4.4 (KitKat). Look for in the US and Canada in May, starting at $130 with 8GB of storage (there will be a 16GB version too).
