 PG/MySql/OSEngineOfChoicewill get left behind simply because the efficiency offered will be worth the price.

Being an option is just fine.  It's not there now.  Asserting that the cloud meme, based on lowest cost marginal
hardware,should dictate a database engine is putting the cart before the horse.

Just not on cheap clouds, if they want maximal performance from the engine using BCNF schemas.  Replicating
COBOL/VSAM/flatfileapplications in any relational database engine is merely deluding oneself.

Not really.  MicroSoft is losing ground for the same reason all other client/standalone applications are:  such
applicationsdon't run any better on multi-core/processor machines.  Add in the netbook/phone devices, and that they
can'tseem to make a version of windows that's markedly better than XP.  Arguably MicroSoft is failing *because Office
nolonger requires* the next generation hardware to run right.  Hmm?  Linux prospers because it's a server OS, largely.
Desktopmay, or may not, remain relevant.  Linux does make good use of such machines.  MicroSoft applications?  Not so
much.
