Just three of many email programs to choose from in Linux. Personally I can't imagine what is so great about Outlook. I've used it, have it on my laptop at work - and still choose a Linux option instead.
I know where this is going. You probably MUST have all the popular proprietary Windows programs or you just can't get anything done.
I boot into Windows for one thing - 3D CAD. I used to do this via a Virtualbox/Win7 installation. It works great for small assemblies but not large assemblies. Not on my older computer.
