Hi,
I have been using my PRS600 for over a month and I absolutely love it! So much so that I'm now thinking of getting another one (cos I actually bought this for my wife but I have been monopolising it since day 1

) Other than reading books bought off the eBook store, I spend a great amount of time reading Chinese PDFs converted from html pages.
Thing is, I have actually seen a Kindle 2 and I can see that its screen is slightly better than my PRS600. But I'll never go for the Kindle due to it's fixed memory, proprietary format (I can borrow eBooks from my library

) and limited support for PDF (must submit to Amazon for a conversion that's not guaranteed to format properly

).
I have heard that the PRS505's screen is much better as it is not touch screen. So my question is: What will I lose out if I were to get a PRS505 instead of another PRS600? I stay in Singapore which does not offer the Sony readers locally so whatever I buy is simply a leap of faith which is why I'd like to get some opinions.
Thanks in advance for your advice.
