The laptop is still very new, so I would guess that's why there are not that many reviews for it yet. Give it a little time and more reviews should start showing up on the site.
As far as recommending the Spectre, I'm a student as well. I LOVE how light this laptop is. The screen may not be 4K, but it's still HD (1080p) and content still looks good. While the speakers are decent, I would still use headphones when watching Netflix. Taking notes is actually pretty good on the Spectre, since the keyboard is surprising great given how thin the laptop is. They keys actually have decent travel distance. If I could complain about the keyboard, it would be that they are a little loud, almost like a mechanical keyboard (I don't think it is mechanical, but I could be wrong).
The Spectre doesn't have a dedicated GPU, it has Intel HD graphics. You could get away with casual games (I like to play Hearthstone on the Spectre), but I don't think you would be able to get away with more graphic-intensive games like Doom.
