Why 'forget about Ubuntu'? I've never been part of a large scale deployment of Ubuntu. We have only tested in very small numbers, dozens. We have over 30k windows computers as well for the 'general employee.' While we get a huge licensing discount for our purchase volume, it still adds up. A guess off the top of my head is that we will spend about $3/month/computer for 365. That's almost exactly the same we paid before on our yearly license: or around $100k. If we switched everyone to Ubuntu, wouldn't we save $100k just on software license, not to mention dropping the exchange server and other infrastructure that makes windows run so well in the enterprise. In our limited testing Ubuntu did everything the general employee needed, email, document creation, spreadsheets, ect. The learning curve was very small, although they were handheld more so than a typical enterprise level deployment.
I would be more than pleased if everyone went to Ubuntu.
Sorry for hijacking the thread OP.
PS. Almost 4 year ago I was one of the Windows8 beta testers ( I was hopeful ). My final writeup stated that Window8 in its current form would destroy the company with the up and coming Apple eco and a maturing Ubuntu OS. Windows8 has significantly improved since then, I've just deployed 200 Win8 machines last week as a non-managed side project. I've received dozens of emails asking for assistance with things like: How do I turn it off, where are the settings, how do I turn off pop-up-blocker? I also deployed 100 Ubuntu systems for the same project at a different location. I've received no emails asking for assistance. maybe they cannot get email to work
