First of all, I'd say is it an Ultrabook that you need? Does it need to be as portable as that, because in terms of specifications, it's nothing special for that price. Although it does look sleek and sexy, and it will run very well, if you want price:performance, which by your description you're not too worried about, this may not be the best for you. (Vaio is great Price:Performance). 
 
Secondly, I don't know about you, but alot of people I know find it hard to type fast on that kind of laptop keyboard, and as you want to use this for word processing and programming, you might want to type fast. Just a thought. 
 
Lastly, in terms of reliability, this is pretty good and as a student, I'd say you would need that. Buying this wouldn't be a bad choice, I think you'd be happy with what you got. 

It should work for you, you don't seem to need too much power. It looks like it's a 15" version of the 900x3c, which is 13" and currently the highest rated ultrabook on Notebookcheck.net. 
 
Personally, I'd find something like that not powerful enough (especially GPU wise) and doesn't offer too much extra (no DVD Drive, not a lot of storage), but if you only need to use word, powerpoint and some small coding, this should be good enough and the light body is definitely very handy and it looks fantastic. Maybe look at some (non RT) windows tablets, which would also work with word, powerpoint and programming, is even more mobile and you get a touchscreen with possibly pen support
