Lenovo's ThinkPad Tablet 2 has been an elusive beast. We heard about pricing in October with promises that it would arrive the same month, but it was held back at the last moment with few progress updates since. Patience, it turns out, is a virtue: the Windows 8 tablet has returned, ready for sale. The promised $649 starting price offers a 64GB WiFi version; spending $30 more adds a pen input and digitizer screen for frequent note-takers, while a $729 version loads Windows 8 Pro for the corporate crowd. No one's likely to put it on their last-minute gift shopping list, though. Lenovo estimates a delivery date of January 7th, which won't be much consolation to recipients short of an IOU.
