So why use it? It borrows the interface of Chrome for Android, it syncs bookmarks, passwords and visited pages, it doesn't limit the number of tabs you can open, it has an incognito mode, it comes with the powerful Omnibox and integrates Google Voice Search.
Chrome for iOS is more about the ubiquity of Google's browser and being able to access your bookmarks and the pages you visit from almost any device.
My other complaint is that Chrome for iPad uses a tab overflow feature that's annoying and far from intuitive. When you open many tabs, you'll notice that Chrome collapses exactly the tabs you've recently used.
When Google released Chrome 4 years ago, few people would have expected that the new browser will become more popular than Firefox and Internet Explorer. Chrome's popularity continues to grow and the new release for iOS will allow iPhone and iPad users to get a glimpse of Google's browser. Those who want more can buy an Android device.
