Apple announces 21 March event, iPhone 5SE and new iPad expected

SURPRISE, SURPRISE. Apple has announced that it will hold an event on 21 March at which we'll no doubt see the launch of the iPhone 5SE, a new iPad Pro and new Apple Watch models.

The invitation is typically mysterious. 'Let me loop you in,' it reads, which is perhaps a nod at the new Apple Watch bands expected at the event, while the colour scheme could also be a hint that the rumoured iPhone 5SE will be available in the same colours as the iPhone 6S.

So what else can we expect from the iPhone 5SE? Months of speculation suggests it'll be Apple's first 4in iPhone since the not-so-popular iPhone 5C, but that it will ditch the tacky plastic design in favour of an aluminium case reminiscent of the iPhone 5.
