Which means that with a few tweaks to add some wholly optional additional capabilities the iPad really could replace your laptop, but it would also continue to be by far the finest tablet on the market.
So, no, not just a laptop. Not just a tablet. It could seriously be what the Surface and the Pixel Slate both desperately want to be.
The Surface is a great laptop and a mediocre to poor tablet. The Slate is ... I'm not really sure. It has access to lots of great mobile apps, but they're phone apps, so that really can't compete with the iPad, which has an amazing and robust app ecosystem.
With a few more capabilities added to the iPad -- optional ones, that you don't HAVE to use if you don't want to -- the iPad could realize the dream of devices like the Pixel Slate and the Surface, which both fall short of what they set out to be.
