Microsoft threw a surprise hail mary in Los Angeles today with the unveiling of its new line of Windows 8 and Windows RT
tablet-laptop hybrids dubbed simply "
Surface." But some big questions remain, like -- when? how much? and who is this for?
Surface is a bit larger than an iPad with an HD display, full-size USB port, Microsoft's next-generation operating system, a built-in kickstand, and a detachable cover that doubles as a flat keyboard and touch pad. That's what we know from today's unveiling, but there's much more that we don't know.
