Reasons for obscurity
Actually, I wonder whether a small point re Roadmaps might be worth making? Roadmaps might be getting harder to come by, because well, certainly in the desktop space, we've been in the "here be dragons" sector of the map for some time. If as a vendor you're resorting to be-ribboned interfaces, and passing cloud-shaped bandwagons, then perhaps you've started to run out of viable reasons for Joe Public/ SMEs to upgrade... CS6, Office 20WTF, I'm looking at you. For vendors wanting to hit next Quarter's tagets, app lock-in tied to forced OS obsolecence may soon become the only tool in the toolbox...
(Why am I getting my coat? Coz I'd still be happy to pay for an upgrade where the bugs are all fixed, and the formats are all open... but, Shangri-La apparently not appearing on any roadmap soon... )
