I just saw a one off from them that I got from one of our IT staff. We are a 50-50 district mac/pc and have moodle installations for Online, All HS credit recovery and general teacher use. Apple wants us bad. They pushed study whiz a couple of years ago hard and tried to explain all the pitfalls of moodle (all of which were wrong). I did visit a school district using it and they were unhappy with it and were extricating themselves from it.
That said it was 2 years ago and i agree that the study wiz spark add peaked my interest especially if it is an easy compatability with an ipod. My questions are about compatability across platform among other things and how well it actually works. If you have learned anything new let me know and i will do the same as i am sure i will be hearing more as apple takes another crack at our district.
