Lenovo's upcoming ThinkPad tablet shown off in Brazil

Lenovo's long rumored tablet made a brief appearance in Brazil this week. During a recent press event in the country of samba, supermodels and the seleção verde-amarela, Lenovo's Jaison Patrocinio publicly flashed the device but stopped short of providing any new details. He did however show the ThinkPad-branded tablet coupled with its optional leather-wrapped case that contained a full-on keyboard and optical tracking sensor.

Spec-wise it should have a 10.1-inch 1280 x 800 IPS capacitive multi-touch panel, a Tegra 2 processor, up to 64GB of storage, front and rear cameras, a full-size USB 2.0 port, mini-HDMI out, a SD card reader and up to 8 hours of battery life in a package about 14mm thick and weighing 1.6 pounds. For reference, the Apple iPad 2 is 8.8mm thick and weighs 1.3 pounds, but lacks certain features like a USB 2.0 port, card reader, or HDMI-out without a separate accessory.

The device will run a customized variant of Android Honeycomb and support up to four input devices -- touch screen, keyboard, optical trackpoint and stylus -- allowing you to use it like a tablet or a laptop. Other business-oriented options will reportedly include anti-theft and remote wipe options, all while keeping the starting price below $500.

According to ZTOP, the enterprise-centric Tablet will arrive within "three to four weeks." Lenovo is also readying a consumer-oriented alternative but the company didn't provide a timeframe as to when this model will launch.
