There's lots of talk these days about cloud computing, the end of the PC era, etc etc. SaaS e-mail (if I'm using those terms correctly) seems like the thin end of a very long wedge. Are document hosting, ERP, corporate databases (those that aren't already hosted, that is), even CAD next? ITT please discuss your thoughts and, if available, your experience with the next generation of hosted applications and cloud computing. All perspectives welcome - user, manager, etc.
