It depends. IVEE7 is cheap and simple. The board costs less than $1.50 (includes wired connectors) and an Arduino Micro (clone) costs approximately $2.50. So basically IVEE7 can be (home-)made for less than $5 (without soldering).

So separate from the plotting function IVEE7 lacks in some comfort (ie commands abbreviation with 2 letters), but has the whole range of functions of IVEE - and offers an additional matrix section.

First I want to improve the code of IVEE and IVEE7. While porting the code I found some bugs and improvements in the original code.

If I had one wish free - I would wish to have IVEE as a (cheap) buyable product on the market with a good hardware quality (like HP calculators). A credit card sized gadget like the Arduboy (with 16 keys) would be very charming.
But that's far beyond my capabilities.
