First of all, excuse some mistakes, I'm not very good at technical English...

So, I want to ask you (just theoretically) - would it be possible to make a hack for PRS505 that would allow us to search inside the books? I'm not very skilled in this hacking and flashing, I don't know the possibilities of the device, I'm just asking.

Oh it is very possible

Really possible? As I read all the reviews, the lack of search feature is the second most mentioned drawback of PRS505 (the first one is the pdf zooming problem, solved by rasterfarian or conversion to another format). By the way, I looked closely at the hacks list. Those "hacker guys" are doing an incredible job!

Personally, I doubt it...

Oh it is very possible

Can you convince somebody to do it? ;)

Well, it is possible to search the dictionary (http://www.mobileread.com/forums/showthread.php?t=22320), so why not books? ;-) (Of course I understand it is something different and of course more difficult, but it would be nice...)
