iOS 9 content blocking will transform the mobile web

Over the last few days I've been testing an experimental content blocker called Crystal, which promises to speed up browsing on iOS. I've been particularly impressed by the results and taken aback by how much removing trackers, ads and other scripts makes a difference over a cellular connection.The content blocker is a major selling point for iOS, in my opinion. On Android, this will always be a hack - third party tools, root, that sort of thing - and never properly integrated into the operating system, even though it should be.Good move by Apple, and together with a lack of a decent Android headset out right now, it's pushing me towards an iPhone when my contract renewal is up in October.
