During Microsoft’s BUILD conference in Los Angeles, Microsoft execs took the stage and showed off a number of new tablets, notebooks and desktop computers running its latest Windows 8 operating system with the new Metro-style user interface. Steve Sinofsky demoed the operating system running on ARM-powered devices, Qualcomm powered devices and even one tablet running NVIDIA’s upcoming quad-core Tegra 3 chipset. One desktop computer, the HP Phoenix, is expected to be unveiled later this week, although full specs on the system have still not been announced. We’re impressed at the versatility of the new operating system and love that it can run anything from a small netbook with 1GB of RAM to a gaming rig running multiple graphics cards in SLI. Microsoft will also be giving out a “Samsung Windows Developer Preview PC” to 5,000 developers at the BUILD conference. It’s equipped with 4GB of RAM, a 64GB SD card, a microSD card slot, HDMI-out, NFC support, Ethernet and more. AT&T will also provide owners of the tablet with one year of free data service with 2GB of data per month.
