Yes. Future is to be able to carry ONE OR MANY input/output appliances whether it's a 3.5", 5" or 13" screen. Up to you. And then have a receiver/transmitter (with sim card) in your iWatch or some other tiny device so that your appliances can send/receive information...or just use your iWatch alone and use voice recognition. Judging from this forum, that would eliminate 99% of heated debates over "too small" and "too big" screens!
