that's the key point why would anyone want to have ANY device with a proprietary OS if they can have Linux or symbian as a secure safe publicly tested opensource OS weeks ago my old laptop OEM vista from Acer with dualboot (openSuSE + vista) got blocked (vista desktop) by Microsoft Inc for totally fake reason. imagine you have a microsoft controlled smartphone and want to call an ambulance, your office or family and Microsoft Inc grays out your smartphone desktop and NOTHING works anymore ... when nokia moves all high end from opensource to Msoft, then bye bye Nokia as a 9 years Nokia-only user.
