Digital boards for recording Math lectures

[joniengr]

Hi,
I am looking for a smart digital writing board for recording my Math lectures. I just have found Wacom Intuos that can be connected to PC via USB cable. Is there any similar product which is cheaper ?

It might be easier to just use the computer an find some software that can handle LaTeX typesetting of math equations. I know there a some WYSIWYG versions of LaTeX around that might help.

I do remember MathCAD that had a WYSIWYG approach that differs from Matlab and it can perform calculations in a relatively freeform way on a page. Doing a search it appears the software still exists but is even more than that tablet.
