A number of apps take advantage of the built-in mic (there is even a free speech recognition app from Dragon/Nuance), and a number of people have reported good results with Skype as long as you are not trying to use BT hardware, which is not supported yet (but will be in 4.0, I think?).
they should make an ipad app section of the forums methinks.
I think we're supposed to be using the main Apps subforum, but whenever I go there it doesn't seem like that's happening yet. (I agree with you, as it happens, but I think if they were going to do a separate forum they would have by now.)
I like this app but I am having trouble downloading resources my professors post on blackboard. It has folders where you click the "+" and the files in the folder drop down, expanding what is in that folder. I can only get as far as the main page where I can download from, but I can not download the files in the folder.
