Thanks.
I've just had an unpleasant thought. Does this mean the ereader application might no longer be maintained (updated for new versions of PPC operating systems) and ebooks no longer released in that format? I always knew my hundreds (several hundreds) of ebooks could become obsolete at some point, but I've tried not to think about it. If that happens, I hope someone will write a conversion program. I'm a law-abiding sort, but I think this is where I'd cross over.
Never mind. I just read the press release.

ops: Still not totally reassured though. I hope it's not like the dreaded vote of confidence just before the end.
