Touch for chrome
This is a chrome 'experiment' you can find these and many more in chrome://flags.
This is a touch optimized version of the metro chrome. It makes everything a bit bigger and gives more spacing, I don't have any windows 8 touch screen devices but if somebody could share this with a YouTube reviewer then maybe they could do a demonstration and record it? But for the most part from what i have seen this looks pretty good and doesn't ruin chrome.
