Hi -I'm going to critique the article itself:
It's flimsy, light, and 'trendy' - not exactly the result of hard-core study. Not too many concrete reasons are given as to why online collaboration tools are *better* or fill specific business needs compared to word.
Despite its warts, Word *works* and people generally know how to use it. It's tested, it's a known entity, businesses know how much it costs, etc. They're not ready to experiment yet.
Obviously online services have a totally different set of pros & cons, but this article doesn't really seem to address those.
Even if online suites were clearly better suited to business than locally installed software, *this* article does not make a suitable case for switching.
My concern is C-level execs who see this kind of stuff and make sweeping decisions for their company based on a trendy 'puff' piece like this.
I would advise them to go ask Gartner or someone who actually knows how to research this stuff. :)
