As you'd expect, we've also looked at it in great detail and posted our thoughts online. "While previous iOS updates were largely a case of install-and-get-on-with-it, iOS 7 takes a bit more getting used to" - but "Apple isn't hurling babies out with the bathwater here. The iOS we know and largely love is still there, but it's been given one hell of a makeover."

The visual changes are largely effective - although the Music app is pretty hideous and the new look is sometimes just too bright: "using Safari on an iPad in a dark room after a long day is really quite unpleasant." But the most important changes are functional.

iOS 7 has learned a lot of tricks from elsewhere, but what matters is how it works

The new Control Center makes it much easier to access key features such as Bluetooth and Airplane Mode, the new Notification Center is handy, Safari and Mail are much better and the whole thing feels much more modern and efficient. Many of the changes owe obvious debts to Android, WebOS and - yikes! - even Windows Vista, but the important issue isn't who thought of them first but whether they make your life happier, and in iOS 7 they do.

It's not all good, though. Maps is good but not great and definitely not as good as Google, Siri alternates between being absolutely wonderful and utterly infuriating, and as with iOS 6 you shouldn't expect all-day battery life if you actually plan to use your device for anything other than the odd email check.

If you're a die-hard Android fan there's nothing here that's going to make you reconsider your life choices and jump aboard the Apple train. If you're already an iOS user, though, it "will make your device feel brand new all over again. We think you'll like it a lot." Are we right? Let us know in the comments.
