Lenovo IdeaPad K1 up for Amazon pre-order, still toting $500 price tag

The IdeaPad K1 is really living up to its name these days, existing merely as an idea and a visualized concept, but not a real deal purchasable commodity. That's changing ever so slowly, however, with an appearance among Amazon's pre-order inventory, where the Tegra 2 Android slate is accompanied by the $499.99 price tag we saw just over a week ago. The major specs are as we've heard them before: a 10.1-inch screen with 1280 x 800 resolution and 300 nits of brightness, a microSD card reader, micro-HDMI out, and, interestingly, a SIM card slot. The latter doesn't quite confirm that we're looking at a 3G tablet, but comes close to it. Also close should be the K1's release date, which isn't spelled out by Amazon, but is expected to arrive any time now.
