3. Lenovo ThinkPad Tablet
The Lenovo ThinkPad tablet is a worthy entry to the company's vaunted business-class notebook brand. The 10.1-inch tablet features the Android 3.1 Honeycomb OS, Nvidia's Tegra 2 dual core processor, and up to 64 GB of storage. There are also plenty of ports: USB 2.0, micro-USB, SD card, and mini-HDMI.
The ThinkPad Tablet has a few unique features, too. The device comes with a digital pen and some strong pre-loaded apps for security and office productivity that are a far cry from the "bloatware" we're accustomed to seeing on new desktop and laptop PCs. And perhaps best of all, Lenovo customized the Android GUI to make it easier to navigate. The ThinkPad tablet starts at $499.
