Currently my company is making a full shift to 'the cloud'.

And as we are a Microsoft minded development company, we tried tfspreview for a while and I ab-so-lut-e-ly love it! Especially the integration with azure websites is great for our webdevelopment projects.
Last month we moved all our projects to tfspreview (technically it isn't in preview anymore) and this week we will pull the plug from our own tfs server.
Here is a nice introduction to get you started: [http://tfspreview.com/en-us/learn/start/connect-to-vs/](http://tfspreview.com/en-us/learn/start/connect-to-vs/)
