Yes it does, but out of the box, it only works on some native apps (to scroll, etc.). But reportedly there is a plug in that widens its functionality to more apps. I'd like to hear more about the plug in.

As for the GS4, it'll sell well, no doubt. It's highly functional and has a large fan base and impressive marketing support. My primary problem is the design and lack of premium build materials. The HTC impresses me more on these fronts and seems to offer the specs and performance I'd be looking for.

And I think that there is still an app gap that favors iOS over Android. It is in the quality of the apps, since the numbers of apps are so high as not to matter. My GF has an Android and pointed this out to me and it is true--even the same title is often slightly better on iOS. I'll likely get an Android, but if there were an HTC One-like device running jailbroken iOS, who knows?
