iOS 11 beta: Should you download Apple's new software for iPhone and iPad?

Apple has released its iOS 11 beta to the public. That means everyone can get hold of the new software, months before it's released – but there's a big catch. Because the iPhone and iPad operating system isn't actually finished yet, it's full of plenty of bugs as well as not being as refined as it will be when it's officially unveiled. That means that using it comes with a huge warning: it might stop working properly at any time, and you can't really complain about it if it does. With that out of the way, it's worth getting to what iOS 11 does actually give you.
