There are some downsides - only basic file system usage on Linux - can mount it R/W but that's about it. I spend about half my time doing tech work in the Linux world and the other half doing reporting, analysis, power point engineering and other administrative work in the windows world. I suggest anyone with a similar mix (or more slanted towards windows) give it shot. For much of my work none of the cloud services are secure enough for usage, so there are some limitations. I was using Google for these activities, and for me MS is the clear winner on this type of service.
So don't focus completely on the bad news with a dropout on a MS cloud service, and open your eyes a bit on their other progress on the user experience with consumer cloud services. You might be surprised. Or you might have your mind made up before you do.
I'm not a shill, I like all OSes from Windows to VxWorks - they ALL have their uses in the right environments depending on your needs.You may note I didn't crap on any of them.
