I've been reading the comments here and I think most are thinking of this the wrong way. Chrome OS is simply not going to be a viable corporate environment out of the gate. That's not even a question (the incremental updates that are automatic and can't be turned off would prevent that all by themselves).
The question is whether the computing model will be enough to entice CIOs and IT Managers. The dream of every IT manager has always been the dummy terminal it was just never viable (Though Citrix solutions and Terminal Server get much closer). If Google can prove they're serious about this they could start to make serious in-roads by the time Microsoft releases Windows 8 (around 2013 I'm guessing)
