This is what happens when you rip out well-tested IT infrastructure that has a reasonable update distribution process and entrust the cloud to update your software for you.

I've never been clear on what CtR describes. The first CtR Office was Home & Student 2010, which was a purchase.
A huge difference for business is that Windows Update allows you to approve/deny updates and cache them on a local server with WSUS, whereas CtR leaves each machine to go talk with Microsoft amongst itself on what to install and mostly cuts your IT staff out of the loop.
I've seen about ten major Office 365 outages since my last major Exchange upgrade? I don't know how beliefs about cloud service uptime being good persist unless your IT staff were really, really bad at their jobs. My house is more stable than a MS datacenter. And by and large, I actually like Microsoft.
I had terrible problems with hosted Exchange from Intermedia. I've had pretty good luck with Exchange on Office 365.
Office 365 support is absolute garbage, they really want to punish you for contacting them, especially so if you've found a bug.
