The main thing they need to nail with this tablet, despite what the nerd in us all wants, is the external aesthetic. It can have all the spec in the world (the screen sounds incredible), but to really do some damage people need to be able to pick this up and feel a viable quality alternative to the iPad. If if feels or looks cheap it will fail. I mean christ Apple can't own every good designer in the world, is it really that hard to make a rival in design as well as technical specifications?
This, no doubt it's a very capable machine but compared to the iPad or even the Surface it has a cheap, even kind of toyish look about it (that goes for both the hardware and the software). But maybe it'll be different in person.
