I was one of the few people that thought people would like it. That is, why shouldn't it be better to have a bunch of tiles on your desktop that have the most important information and then you choose the one you really want to concentrate on full screen? Well, of course the problem is you aren't using a tablet. It's trying to fix something that never needed to be fixed.
But yes, Linux is great now and most people on the site can easily debug potential problems they run into on it and not look back.
It also suffered from a lack of relevant applications. The apps I used were a terminal emulator, a web browser, Word, Excel, Project, and a few other old Win32 type apps - none of which were going to become "modern" apps in any useful way.
