I just acquire mine a day ago and I I will agree with you. (like and want for improvement)
I am very happy with my PRS-505S, it is very pleasing to read with.
And I have to admit that when i turn a page, I do feel a little bit like an alien that blink twice sideway.
That too would have to be work at.
I am now looking forward taking the plane and going to England in a few week.
