Let me explain then.
With WIi U it really comes down to two things for me - the HDMI output quality isn't quite on par with the solutions I was discussing (slightly softer and darker) and, more importantly, it requires using ISOs. I can understand that's not an issue for some but that's a HUGE turn-off for me personally. The double menu element is also annoying (though you can boot straight from the quick launch on the pad - but it still has to load for a while). If you don't mind it, though, it's a solid solution for HDMI GameCube gaming on the cheap.
Now the Wii comments - do your homework, really? Come on now, you really think I wouldn't know about that? The issue is that the CC still requires you to connect it to a Wii-mote with its own batteries. It's similarly annoying to having a sensor bar up.
...but I can agree that brushing off the Swiss aspect is hypocritical and, for that, I can apologize. I have mine configured to auto-boot at startup so it's minimal fuss but the configuration isn't that simple and it requires extra hardware. Really, though, the majority of my collection is NTSC-U so I haven't had to face the PAL problem TOO often. If your entire collection is PAL then it's definitely similarly annoying to using a Wii.
The main issue for me with Wii is that, for 480p, I find the component video output to be much noisier and lower quality overall. It looks bad on my OSSC compared to the GC component cables or the GC Video adapters. For 480i then, on my PVM, I run into a region annoyance in that the NTSC Wii doesn't support RGB SCART which is how my PVM setup is wired. Running component to it requires me to pull out my setup, disconnect the BNC plugs, connect some BNC to RCA adapters then plug the Wii in. It's kind of a hassle so the Wii is basically not part of my setup as a result. So, for me, it's just not a good fit at all but that doesn't mean it can't work for others.
So what I've said isn't a mistake at all but I was, perhaps, a little too harsh. So apologies for that.
The main thing I'm liking about this EON adapter and why it's such a good fit is that it can do analog and HDMI output at the same time. This allows for easier capture while playing. I can send the HDMI directly to my capture gear while the analog goes to my OSSC for line 2x 960p mode. It's working very well indeed.
