Microsoft needs to get the onscreen keyboard working at bitlocker screen, so I can enter pin without always having keyboard attached. I don't want to carry keyboard with me at all times but company policy dictates bitlocker. Dell just released a BIOS update for the Latitude 10 Tablet that has onscreen keyboard now to enter bitlocker pin. It is FANTASTIC!!! Come on Microsoft it's doable. Loving 8.1 Preview on the Surface, good stuff.
