Good stuff there! Beats bringing the laptop out to the garage!
I have a "D'OH" moment before every brew session when I remember I need to print the recipe.
I print out every recipe, and keep that on a clipboard in the brewery. And then write notes on the paper as to mash temps spikes/drops, OG, FG, Kegged date, or anything else that might happen. Then, once beer is sold, I update beersmith with all those notes, and move on. I generally have three, 10 gallon batches at different fermentation/Kegging stages at any given time.
