Hello everyone!
As you can read in the title, I'm trying to decide which will be my first ereader but I feel kind of lost at the moment and good advices would be much appreciated.

I apologize already for my English and I hope it will be understandable, if you need clarifications just ask me
I'll try to explain what I'm looking for:
I read lots of pdfs on the computer, both for university and for fun (for example chess books) but I'm sick-tired of it as it strains my eyes a lot.
I reckon buying an ereader would be a good solution, at least for my eyes, even if ereaders are not regarded as the best device when it comes to pdf handling.
As a workaround I was planning to convert pdfs into epub using calibre, would it be an effective solution?
Mostly, I'll be uploading pdfs from my computer and I won't be using online stores that much, at least at the beginning. I usually take lots of notes as well, so a fully functional keyboard with an easy manageable notation system would be great.
I'm going to carry the ereader with me everywhere during the day and I'll be using it a lot, so the "sturdier" and less buggier, the merrier.
I don't care about the design and the front-illumination would make a nice addition but not necessarily required.
As I'm a jobless student, I don't want to spend more than 150€ (200$) for an ereader.
I have to exclude the 2 Nooks as in Italy they're not available at the moment. Today I had the possibility to try directly the two kindles: although great in the other aspects, It felt strange taking notes using the buttons of the kindle 4 and liked definitely more the paperwhite touchscreen.
Still, I haven't tried the other brands, particularly Kobo which seems more interesting than Kindle for some aspects (the epub support and the memory slots).
Any suggestion would be greatly appreciated! looking forward to hearing your opinions, cheers!
Nicola
