That is unless someone cal tell me how a move to an [open source alternative] would be better. Even these OSS alternatives have to be supported. The last time I checked, their support was anemic! Just ask the University of California.
Are you retarded, or just trolling/FUDing?
The article you linked to doesn't mention any OSS alternatives, nor any support costs/availability of anything. (Also, Mashable is the best you could come up with for a source?)
What the article you linked to (titled, "Major University Dumps Gmail Over Security Concerns") actually discusses is that the University of California in Davis just stopped their pilot roll-out of Gmail due to concerns that it wasn't secure enough. In actuality, its not clear if Davis would even be allowed to use Gmail at all, as the article notes, "[school officials said] outsourcing e-mail may not be in compliance with the University of California Electronic Communications Policy."
Later in the article it mentions that other organizations (such as the City of Los Angeles) are adopting Gmail. The whole thing is hardly damning of Gmail, and doesn't even mention OSS.
Mods: Don't just assume that someone's citation backs up what they're saying. Parent is off-topic and not particularly insightful.
For me, I can say that when my previous employer switched over to Gmail for our email it was a huge boost to uptime, and a dramatic drop in cost compared to the (unfortunately) poorly supported in-house Linux-based OSS email server and the Exchange server we were quoted.
