IMO, it really depends on how much time your sister-in-law spent on the 505. I have both a 500 and a 505. Every now and again, I forget to charge the 505 and tried to use the 500 to read with and I find the lower contrast just so frustrating after the brighter 505. But I didn't think it was so awful until after I'd used the 505.
Also, since I hoard books and have more than 600 on my SD card, I strongly prefer the somewhat improved Contents listing on the 505. That wouldn't be as big a problem to get used to, though, if I had to go backwards. I don't like either one all that much, so it's just a case of being less annoyed.
The new firmware on the 505 is nice for reading ePub, if you're willing to put up with Adobe's DRM scheme. Since I don't like Adobe's Privacy policy, I choose not to use it. And I haven't experimented much with making non-DRM'd ePubs yet, to know whether I'd prefer them to LRFs. So far, the benefits of the ePub seem to be tied to the ability to write HTML/XML code. And the last time I coded HTML seriously, it was version 3.2. I'm more than a bit out of date and haven't been willing to take the time to learn the newer techniques.
So, I guess my point would be - if your SIL didn't get too used to the 505, she'd probably be fine with a 500.
