Ashley : My thinking about Html 5 is great. I prefer Html 5 than flash, performances are better and we can see that with C2 of course. How you said the problem isn't really the desktop or html 5, because we know that C2 is made arround this technology, this more mobiles, how you said in your post.
You said :
o yes, we're stuck with some difficulties in the mean time, but I am totally sure given time everything will be much better, and for right now today, there are workarounds like directCanvas and CocoonJS, as well as things like the Safari for iOS browser working very nicely, especially with iOS 6+.
That means that all is not completly stucked :) and with time and patience, we could have better performances for mobiles with Cocoon or AppMobi etc...just take time to technology to be completly ready may be :)
I prefer an answer like this, that is for me, more understandable.
And I have always supported C2 ^^
