Please consider that school and University may require Closed source and Windows only programs.
I did study Psychology for 3 years now and Pandora was my main tool (besides a Linux Laptop)
Power won't be a problem any more but some things you have to consider:
1: Laptop can give you 2 screens with an external Monitor.
It is really useful if you do write longer texts and make presentations.
2: The closed source windows problem.
3: The lack of acceptance and support.
In my University and subject I was on my own.
A lot of people did upload documents as .docx and .pptx instead of .pdf.
Linux can open it but might crash some formating.
Linux way is the hard way.
4: No portable big screen and Keyboard
Laptop might be a lot better to work with groups
5: No VGA
I hate that to be stuck with old technology but in my University I had to use VGA for my presentations.
Pyra won't have it. And believe me, you'll do a lot of presentations at University.
(DisplayLink or Converter will solve that problem)
Now the benefits:
1: Always everything
There is a big chance that University is more pretty modern and you'll get a lot as .pdf.
So when you have your Pyra you have your Games, music, texts, simply everything always with you.
Sit in the train? Read some texts and take Notes (I did it and it worked out nicely. Alt + TAB let's you cycle between windows really fast and easy).
Storage is no problem.
A Laptop might not be with you all the time.
2: Battery
Will not run out
3: Great to take notes and study
In University I never did print one page to learn from.
We got all the presentations from the teachers before the lesson.
I did take notes with my Pandora (annotate PDF. Easy and fast with Xournal).
Afterwards I could go out and learn wherever I wanted.
With the touchscreen and keyboard it's possible to annotate free lines and write with nicely readable computer letters.
That's my experience.
Because of the 2 screen issue (you can use 2 with Display Link. I use HDMI with Pandora via USB) and the Windows domination I would not use Pyra as my only device.
If your School/University will not accept your Linux programs you're lost (Exagear and Wine can not replace full Windows)
Pyra will be great for (I guess) 80-90% of what you need it for but the last 10-20% might make it useless for you.
Maybe wait and see what's possible with it.
