Ahhhhh. I got about 9 kinds of excited but then realized this is a MS product and allows the running of Ubuntu in Windows.
Alas, I need to go the other way. About 10 years ago I'd had all of MS that I could take (a 2 hour update in the midst of an important to me project) sent me to Linux to stay. My desktops and laptops from then on were strictly Linux.
I really like that MS is doing this, people can and will find the utility of open source OS. For me, I'd really like access to a few bits of software that simply isn't available to me.
