Trim Slice: a $250 Tegra 2 dual-core ARM Cortex-A9 PC – Computer Chips & Hardware Technology New paltforms like Nvidia’s Tegra 2 are allowing for some very powerful tablets to appear on the market, usually running the Android OS. But Compulab has decided to use Nvidia’s platform to create a tiny, feature-packed desktop PC instead. The Trim Slice is the smallest nettop I believe I have ever seen measuring just 130 x 95 x 15mm. It’s also possibly going to be the first consumer desktop PC available based on an ARM rather than an Intel chip solution. At its heart is a Cortex-A9 dual-core processor (Tegra 2) running at 1GHz coupled with an integrated GeForce GPU, 1GB RAM and a 32GB SSD. Compulab state that the PC will ship with Ubuntu 10.10, but plans are underway to support Android Honeycomb too, making this an ideal platform for Android development. Anyone seeing this and wanting one won’t have long to wait. Read more at ARMdevices.net
