I don't want to come off as an apologist for the company, but the head of the project did have an interview with retrorgb where he admitted the company made poor communication decisions and has been making progress, albeit always slower than anticipated.
To answer your question from my personal perspective, I believe the system has a lot of potential. I also think it's going to be hampered by the cost. The company built a lot of the uphill battle itself. I have some experience with emulation boxes myself, and I don't find them easy. It's not there all built and ready to go, each system has tons of configuration options, and trying to set universal controls still often leaves a systems controls having to be adjusted as you switch. You need a front end, you need to load roms, and if your using one with fancy scroll wheels and massive game lists, the menus, sub-menus, duplicates, and visuals are not cleanly presented or quick to access. If you decide to use standalone emulators, every UI is different, and emulators very in quality and features. Stuff like mednafen standalone is more like MS-DOS than a program designed for Windows in mind. Some things run better on Snes9X, some run better on bsnes. Want graphical enhancements or need to tweak settings? Your emulator of choice might have dozens of settings available, some with jargon you may not understand off the bat. Want an all-in-one? Retroarch claims to be the answer, but the interface is buried in menus and options, and in my experience, often has settings inexplicably reset or just decide it will crash on boot whether the installation is fresh or not across multiple pcs running different versions of Windows. PC and emulation boxes are great, but they are DIY from the software side. They aren't appealing to a lot of gamers, because they require lots of time and effort.
The idea of this machine is that everything is ready to go with no configuration needed outside of choosing a controller to use. Discs and roms can be dumped, so they only need to be read once. It's pretty clear they are putting tons of work into a clean UI that is good at choosing the right images for games instead of all images for them. The fact that the emulators are also being tweaked for the hardware configuration is encouraging too. They even have Steve Snake of Kega Fusion fame on the project, and in my opinion that is one of the best ease-of-use emulators that has ever been made. There's lots of good here with the bad, but the bad took me from excited, to very disappointed, to waiting for impressions from other people of the full product line.
Right now I have an OSSC, and I'm happy with that, but it's also hard to have all of my systems setup. I have to keep half of them in a closet.
