Correct!

Quote:When I look at this calc I see a very nice piece of hardware programmed by lazy programmers.

Couldn't agree more.

Quote:So how are you guys overcoming these step backs?

Mostly by not using it often.

Quote:I would like to hear some tips and tricks, and listen to what you guys have done to improve your calcs.

Vector cross product
cross-product function

Dedicated polynomial root finder program
A "Cadillac " Quadratic Solver for the hp 33s and HP35s
Explanation: Solve the real quadratic equation \(c-2bz+az^2=0\) for real or complex roots.
Not for the HP-35s but maybe inspiring: Short Quadratic Solver (HP-42S)

Matrix support
A Matrix Multi-Tool for the HP 35s Programmable Calculator
