I just picked up an HP 35s, and I'm curious what kind of calculator's does everyone else use?

I programmed my 48GX. I've got concrete working and ultimate stress calculations. I have to enter bar sizes, thickness, cover, width and a couple of other parameters. For me, it's quicker than a spreadsheet. Plus, I've never figured out a good way to include the spreadsheet in my design notes. Since I have to transfer the formulae and values anyway, I'd rather do it from my calculator.
 
When I was denied MathCad, I used string commands in my spreadsheet to write out the formula.

equations can be written in Excel (for documentation) by inserting a microsoft equation object. This provides a much more readable formula.
 
Can you link the Microsoft Equation object to the values you calculate? I thought it was just basically a fancy word processor and you had to type in all the numbers by hand.

I'm talking about something like

=concatenate(A2,"+",B2,"=",C2)

where A2 & B2 are values to be added and C2 has the formula =A2+B2

It's inelegant, to be sure.

no, it is not linked to spreadsheet cells - just a way to display a complex mathematical equation. It seems like your concatenate function is requiring a lot of hand work also and not able to show some of the symbols such as square roots, stacked fractions, powers, subscripts etc.

see example spreadsheet

I agree, my concatenate function is ugly and not very versatile. However, there are ugly ways of putting most formulae in one-line formats, and it's the only way I know of to have formulae written out in a updatable spreadsheet.

Better would be to use MathCad.
