Another Android slate has joined the party. As expected, Lenovo started taking orders for its new ThinkPad Tablet earlier today. The cheapest device will set you back $499 and sport 16GB of storage capacity and Wi-Fi connectivity. Right now, Lenovo is quoting a tentative ship date of August 29.
Folks with deeper pockets can splurge on the $569 and $669 versions of the device, which pack 32GB and 64GB of flash storage, respectively. Both can connect to 3G networks. Optional accessories include a $70 Tablet Dock, a $40 digitizer pen (which is apparently supported by all three ThinkPad Tablet variants), a $50 Folio Case, optical mice, and other miscellaneous nick-knacks.
In case you missed our coverage over these past weeks, the ThinkPad Tablet comes out of the box with a 10.1" 1280x800 display, a Tegra 2 processor, 1GB of low-power DDR2 memory, front and rear cameras, a card reader, USB and HDMI ports, Bluetooth, and a two-cell lithium-polymer battery rated for eight hours of run time. At 1.65 lbs, the ThinkPad Tablet is a tad heavier than the iPad 2. (Thanks to Liliputing for the tip.)
