I'm a manager in an in-house corporate IT dept. Far from running scared from this kind of thing I'm constantly trying to get the rest of the business to except off the self software for all the little tools that they ask for so that we can focus on the key business differentiators.

Problem is, they're a big company and they want slick corporate branded stuff that integrates with our ActiveDirectory and where the drop downs have sucked values in from other apps so it all just works. Which is fine, only, it costs loads and its in most cases it's not worth it.

I think it'll be hard for a lot of big corporates to accept that it's better (for example) to adjust their business to Zoho CRM than to hire people to adjust SAP CRM to their business. I think a few startups will have to adopt things like Zoho and then grow big, before the incumbents change.
