Acer is expanding its tablet lineup with a new budget-minded 7-inch slate running Jelly Bean. The Iconia B1-A71 pairs a dual-core 1.2GHz processor from Mediatek with 512MB of RAM for a machine that certainly wont set any benchmark records, but wont hurt any wallets either. The rest of the specs, like the WSVGA screen, 8GB of storage and lone 0.3-megapixel camera are certainly also helping keep costs down. At 11.3 ounces and 11.3mm thin it's a pretty svelte device, especially considering its expected starting price of under $150. Sadly there's no concrete time frame for release.
