i think atleast 2 unless they get their acts together (nope:mike and jim) or something else speeds things up (hopefull), but i hope soon after they push a qnx os. then every existing playbook should be updated to honeycomb qnx os. just think alot of the patent wars will be extinguished, qnx security and smoothness with a nice honeycomb cover. then android really can get into the professional realm, bb os for all it faults is not easly exploited. the last hacking was the web browser, though it was based on apples design. rim quickly fixed that so as to say everythings fine this never happened. but only time will tell, i hope im wrong in loosing faith in rim but yeagh not if mikey or jimbo are at the helm.
rim really needs to just dump os 7 and forget it ever happened and expidite a qnx os phone and the advancement of tablet qnx.
