Well, perhaps IT's use of specialized local executables was due to a shortcoming that
the transition could be as easy as re-writing the executable as an app or extension...
Perhaps one could start off a company that does such a thing for other companies (although any respectful IT group should be able to pull-off writing their own code).
On the flip side, with ChromeOS in the workplace the need for IT guys to fix/maintain/troubleshoot company computers will lessen, no? Seeing as all updates etc will be auto-cloud-o-matic...
Regarding "Chromebook is for more simple tasks" (from the first post) I hafta disagree. Like it was said above it's all about the apps and there are some pretty powerful and complex apps out there like graphic calculators, audio editing, and CAD!
If a inter-app communication standard developed that would be amazing... Like... say your online file storage system were accessible to all/most your apps such that the design sketched I scanned and stored online could be edited, then imported into CAD to rework precisely, then converted to a PDF I could then send out by email to colleagues along with the CAD file - all from the cloud. Would that be a good idea?
