We're still struggling with the Raspberry Pi and yet another lovely device is announced, the PengPod Linux tablet:

Pengpods have an Allwinner A10 chip with ARM cortex-a8 CPU. Same single core CPU as in the earliest iPad. A10 specs:

ARM cortex-a8 reportedly has two coprocessors which can both do floating point operations: the non-pipelined VFPv3 unit and the pipelined NEON unit for integer and 32 bit float SIMD processing. You must convince the compiler to do the bulk of the work on the NEON unit, for speed. That is a matter of compiler flags and coding habits. See for example this (old) article:

Though PengPod will be more powerful than Raspberry Pi, in terms of hardware it is still a toy like iPad and Android tablets, which could never attract my interest. So what makes me looking forward to the PengPod so much? It must be the operating system. Good old GNU tools, Synaptic, and all the packages so helpful to use a computer in the way you want it. Such tiny devices, still able to run a full Linux, it's just cute.
