Like most Linux-based operating systems, the biggest challenge Leap faces is the GUI. I've found that while all of them are stable, there are glitches that occur from time to time, including lost functionality going from one version to the next. But these issues are more prevalent with the integrated options, and not the O/S itself. End-users are more accustomed to point-and-click solutions they find on M/S-based operating systems. Linux requires a little more involvement than that, but I've found that SUSE has embraced the notion that similar functionality can be achieved in an 'X' environment as well. It just takes a little more effort to get there. "Major" mass adoption may not occur until third-party application providers design their applications to run in an 'X' environment, and not just for Windows. This will be dependent on them, as they determine market demand and whether there is any real return. There are those who have provided powerful tools and application suites, such as The Document Foundation's LibreOffice, that are very competitive, and are opening the eyes of regular consumers, which will help in spreading awareness. Time will tell, but I look forward to what the future brings.
