Apple's 21 March event is sure to spring a few surprises

The invites for the Apple's much-talked about 21 March event are finally out! If media reports are to be believed, Apple is all set to unveil a 4-inch iPhone se and a 9.7-inch Apple iPad Pro at the event.

iPhone se

The phone will look like the iPhone 5s, the most popular Apple smartphone in India and have all specifications of the iPhone 6s - including an A9 SoC chip, the M9 co-processor, smarter cameras and the popular Apple Pay, Live Photos and Touch ID.

Apple has already removed its iconic iPhone 4s, its first 4-inch screen smartphone from India - a hint at the impending launch of the next device, which is expected to be as powerful as the latest iPhone 6s.

9.7-inch iPad Pro

As far as the specifications for the mammoth iPad Pro are concerned, the device is said to be similar to that launched last year. The device may sport Smart Connector to support Smart Keyboard. It may also come with an Apple Pencil.

These are the key developments so far. More to come as the event draws near.
