The Android Open Beta currently only runs on NVIDIA tegra devices - and for some good reason because especially those new tegra 3 chips are pretty powerful and cool. (I personally like the 250 (!) USD new Tegra 3 device announced at CES) - Also we come from a PC & console development background so working with NVIDIA was kind of natural for us :)
However of course we also want to support all the other Android devices and therefore we looked into some statistics what other devices are out there and to figure out the most important devices. We found the following statistics which is really interesting and we wanted to share with you - as expected the Samsung Galaxy S2 is the most important Android device .. .however it only has around 10% market share in total! Still it will be one of the first non-tegra devices we will support.
