Have you looked at the enTourage eDGe? It's no longer being made (sadly) but it is almost perfect for what you want. 2 screens, hinged like a book. One is e-ink and one is LCD. It has a voice recorder, Wacom penabled stylus (needed on e-ink, LCD is touch). Has Wi-Fi and USB port, decent speakers, good forum support here on MobileRead. If you can find one you might like it!
Oh, comes in 2 sizes.
