RIM Co-CEO Mike Lazaridis announced BBX at the Devcon 2011 keynote. He states that it brings together the best of BlackBerry and the best of QNX into one amazing OS. He goes on to explain that the QNX architecture is safe by design without compromising on real time, multi-core performance.

Does this mean that none of RIM’s operating systems will do email and calendaring now?

Oh and the other big news from the keynote:

Mike [Lazaridis] is excited about using the PlayBook with your thumbs, like a BlackBerry phone.

Well now, that’s something that will certainly spur sales.
