The body is plasticky but has a metal frame underneath. The screen is also not too bad. They both come with 16GB of storage. The 1.5GHZ dual core TI OMAP 4440 SoC and SGX540 means this is one of the fastest Android tablets. I suspect it the hardware is faster than the Tegra 2. Since the SGX540 is clocked at 380MHZ and the SGX543MP2 dual graphics processor at 200MHZ the G9 series maybe not too far behind an iPad2 in graphics performance.
Not bad for around £200 for the 8" tablet and £250 for the 10.1" one.
