Nokia vs BlackBerry - Sync'ed failure

Not sure if this should belong here but it concerns Nokia:



That's a fascinating graph. Either it shows an amazing trojan horse job by Elop to bring down BlackBerry at the same time - he's a Canadian after all (/s) or that sometimes different factors all come together to push away the incumbents. Also I wonder how Palm would've fit here even though they didn't have the same amount of momentum as these two players did.
