Tim is on to something here. Methinks there is indeed something distinctly wrong with enterprise systems/enterprise computing in the same way that "enterprise class coffee" or "enterprise class combustion engine" sound distinctly wrong.
Lets take a potted history of how computing has evolved. Where in the ecosystem have the innovation and growth and new "standard models" come from? From enterprise class down or consumer class up?
The latter in most cases I think. Something cool gets invented for use by the masses (or by academics) and then "professional" users look at it and say "Hey! I can use that in my business."
I think a comparison with digital photography is not without merit. There are entry level cameras, there are good-enough cameras, there are prosumer cameras and ... well, after that it is a fuzzy line. Every year - or so it seems to me, something that that was professional-only the year before becomes prosumer and from there often goes all the way down to consumer.
Databases, hypertext engines, word processors, no-nonsense web services...all being born in the non-enterprise space, all climbing their way steadily into what I think of as a prosumer computing space. The big question - how much "enterprise computing" is gradually morphing into prosumer computing? I.e. how much is increasingly based on essentially the same technological bits the masses use for knocking out database apps and editing docs and creating presentations...?
Will there much of anything left which is truly enterprise only?
