Logitech sells notebooks with special dots printed on the paper to digitize the user's strokes.
notebooks on specially printed paper.
My experience with Logitech is that its explicit support of the USB standard allows its products to "just work" on the Mac. However, I am not willing to buy a digital pen and accessories to test this hypothesis.
home page is the official "Made on a Mac" banner. That's a pretty good hint that the product supports the Mac. A visit to its online store reveals that Pen-it is a Mac-only digital pen solution.
The Pen-it bundle includes a Maxell digital pen, Pen-it NOTES software, and an A5-size Pen-it notebook. I am, however, concerned that this bundle may be a rip-off. It is more than twice the price of the equivalent Logitech kit. However, I don't know whether or not the Logitech kit will work on the Mac.
Some advice: If you ask for help in the future, then demonstrate that you have the capacity to use the help you are given.
