Next Generation mobile devices run HTML5 games with 60 fps after all.
True but not completely, since a lot of weaker SoCs out there still struggle.. Intel's current Atom is a dog, it managed to run my game on Chrome at 15 fps, whereas my Nexus 7 tablet runs it a 60 fps.
Likewise, Tegra 4 devices are horrible in comparison and its not even that old.
While new stuff from here on out should have no issues, the majority of the mobile market is still on older hardware.
But I do feel HTML5 is the future, its just I would like to be able to sustain myself until that future is realized, and with CocoonJS loading 400mb into the ram at the start, more than half the mobile market is automatically non-valid for my game. <img src="smileys/smiley19.gif" border="0" align="middle" />
