You could wait until the release date and then ask questions when those who have pre-ordered start receiving it. There are a few Tama-Talk users (including myself) who have pre-ordered one and I'm sure would be more than happy to answer any questions once we get a chance to play around with it. Perhaps the ID L will be very similar to the current ID..or maybe it will be chalk full of new features! I'm sure we'll find out more once the release date comes closer - and of course when users actually get their hands on it.
