For ppl with tiny eReaders, how did it affect you?

Hi all,

I am currently thinking of replacing my ereader, and originally thought of a booksize, but I see the phone-sized (and even smaller) ereader is getting a lot of attention lately and kinda wonder... Is the screen size convenient to you? is the often pagination hindering your reading flow and speed? would love to hear what devices you have and how you like them!
