The sea isn't boiling hot, and the last time we checked, pigs had not grown wings.
But we did notice that faculty and students seemed to need good but inexpensive college workbooks!
Workbooks should provide interesting and meaningful course support for contemporary topics.

In my own teaching, I use a Sansa Clip for audio recording and FlipVideo Ultra for video recording. Both are economical but produce high quality results. If you're faculty and exploring new approaches, check out these items at amazon.com, from whom I have bought several of each. (Disclosure: I don't have any business relationship with the companies that make these products or with Amazon, other than that of being a happy customer. I don't get free products from them, discounts, or one whit of benefit to plug these products; I have just personally found them to be very good products in my classroom use of them. The FTC apparently requires anyone saying anything nice about a product or vendor to make this kind of disclosure and if you don't, they want to take quite a few shekels from you in punishment for not being candid. Probably a very good idea so we are all more aware of biases that may be present).
