Well, I understand what you are saying and I agree that you are one of many, but I disagree with your analysis. I use mostly Microsoft technology and most of what I use is open source, from .NET to C# to NuGet to many, many frameworks. I am very oriented toward open source and very comfortable in the .NET world. It's very similar situation to a Mac user.

As far as storing data I also have my "own cloud" and I also use Dropbox and SkyDrive. I like all of the above and I find Dropbox extremely convenient. However, I do have a concern that Dropbox is not as secure as SkyDrive.
