Having seen the demos, I am convinced this is the biggest advancement since the introduction of the iPhone 4 yrs ago. They will sell at least 20 millions units to their existing subscriber base in the first 12 months IMO. Whether they grow their 80 miklion subscriber base will depend on vendor support and apps -- and they seem to be locking and loading in these areas too.
Psyched for 2013.
Go RIM !
