50g

I have wanted to start a discussion on this group on methods with the
50g for some time now. I am wondering if others in the group are
interested in such a discussion.
I think the first topic to broach is when do you pick up you 50g in
preference to your spreadsheet, or mathematical software.
As a note I am wondering if there are ways to integrate spreadsheets,
mathematical software and the 50g.
