Lenovo's 9-inch IdeaTab A2109 has surfaced at Best Buy under the moniker "IdeaPad." The Android 4.0 tablet is both cheaper and more powerful than the S2109 that launched in July, with a 1.2GHz quad-core Nvidia Tegra 3 processor and 16GB of storage. The device isn't set to be available from Lenovo until next month, but if the Nexus 7's screen is just a bit too small for your tastes, you can pick one up now from Best Buy. According to the retailer's website, the IdeaTab A2109 is available both online and in stores for $299.99.
