As for iOS, there are a couple of nifty new features that users will get a kick out of. Holding down on the back button will bring up the history tab, and will allow you to quickly access any page that’s stored in your history. Furthermore, you can also quickly share web pages through Messages on iOS.
Sadly, the iOS update of Chrome resulted in the app crashing every time I would start it up, so if you’re still on iOS 5.1.1, let this be a word of warning if you’re thinking about upgrading. Hopefully Google will soon release a smaller, incremental update to fix the bugs present in this big update, but for now I’m stuck with an unusable Chrome app.
