Hi
I tried Kobo h2o and aura one and in both cases I found it extremely challenging to touch the right spot on the small note reference number to be able to read a note (or even to highlight exactly the right portion of text I try to highlight - but the problem is more important for notes reference number, sometimes it needs several tries).
I now experiment with a kindle and I'm impressed it's so simple: it just works. For essays it makes this ereader way more comfortable than any kobo I tried. Which is a shame as Kobos are more 'open'...
My question is: are all Kobo models similarly poorly sensitive on the touch layer / is it hard to "click" on the small number to read a note of each of those, or are some models really good / as comfortable for that as the paperwhite is?
