I'm not sure if you're interested in a touchscreen, but the Zenbook Prime generally isn't readily available with a touchscreen yet. I personally like the Duo 11 quite a bit for its portability and really sharp 1080p display, but the Vaio T will get you the same processing and graphics power with a larger keyboard, which might be handy for typing in school.
