Yeah, that's what he said to me, he told me that's actually a "copy" from the surface pro 4 but in a cheaper build with some more "plastic" as cover in comparison to the surface. And also that the pen "software" wouldn't be as perfect as that from the surface (?).
How long do you own your surface pro 3?
Yes, that's what I'm thinking about. I got at least 4 more semesters to go. Since I bought my Nexus 7 with a keyboard cover, I've been making notes by typing on Adobe Reader (for some pdfs handed by the professor), on google docs and others for example, depending on the course and provided ressources. And I must say, without a pen like the surface one, it's more difficult to select things for editing the text, etc.
One big thing that frightens me is the price, it costs a bit more than my laptop and tablet together... but it's so nice and surely amazing to work with and also to sync all documents without issues.
