Thank you all for the answers. I appreciate you taking the time to help me with my choice.
I have decided to go with the PW2. In my country I don't have the possibility of trying them both in a B&M and since I didn't hear anything negative about the PW2 from you guys I'm pretty positive I will be happy with it
P.S. Just wondering... Does RAM matter for e-readers? And how much RAM do the PW2, Voyage and Aura (HD / H2O) have?
