A relatively new name in the tablet-space is PengPod, made by Peacock Imports, a Florida, US-based outfit. The PengPod tablet runs Linux on ARM/Allwinner SoC hardware.
So instead of just running a pure Android tablet, you get the option to run your favorite Linux distribution and Android in dual-boot fashion, provided your Linux distribution has an edition for the hardware.
Neat. So for $160'ish you get the top of the range PengPod with a case and keyboard and 32 Gb of storage. You can use Android or GNU/Linux. Sounds like a winner to me.
