I can tell you that we (EFX-TEK) abandoned the ISD1700 after receiving information from Nuvoton (after a lot of *persuasion* on my part) that there is a problem with the die when run at 5v (you need to drop it to 4.3v) and using 12kHz sampling.  During the course of many conversations their engineer said to me, "Well... the guy who wrote the documentation never actually used the chip and we fired him."  That's supposed to make me feel better?  Then they suggested that we redesign our product around one of their other chips.  I told them if we had to re-design, they were out; we did... they are.  

Our product (which will be released shortly), called the AP-16+, uses a Propeller chip to play WAV files from an SD card.  That's not without its challenges (the WAV players in ObEx have a problem with noise -- I got help from Chip Gracey [creator of the Propeller] to fix this).  So... with Nuvoton, I have to deal with an "engineer" who barely knows the chip and cannot point to any problems in my source code; with Parallax I can go right to the top to solve a problem that was somewhat serious.

Sorry... rant off.  Nuvoton cost EFX-TEK a lot of time and money and I'm not happy about that.
