The 950 has a much larger memory and is more stable so I don't think it's really an issue.

I agree, but anyone concerned about what you would do if some internal file did become corrupted should know that the PRS-x50 readers DO have a 'Restore Defaults' and 'Format Internal Memory' features that can be used if needed. Along with the
hidden hard factory reset.
These are a little drastic though because they will delete everything, so you not only loose any books you have loaded, but also end up deleting your current DRM authorization so then have to reauthorize the reader.
So I agree, these are last resort measures that are not routinely required. Nice to know they are available if needed though.
I have only had one lock up that required a 'soft' paper-clip reset on my PRS-650 and that was related to a EPUB book with rather extreme internal formating (thousands of pages with more than 1200 internal 'chapters'). Even that book was fine until I did a complicated multi-word search for a specific phrase inside the book. All the slightly less complex searches completed in less than a minute, so after a half hour or so, I figured that I had managed to lock up the reader and did a simple paper-clip reset and after that everything was fine. I didn't loose anything.
Badly formatted EPUBs can probably lock up ALL the current readers (not just the Sony, but the Nook and others as well), because they are all based on the same Adobe ADE mobile code.
I have over 1250 titles on my 650 now, including lots of amateur formatted public domain material, and have at least opened most of these titles to check them, and with the exception that single questionably formatted EPUB, I haven't had a single other problem with ANY of them.
