As someone with an abbreviated, wireless keyboard (which we love), we do occasionally run into moments where we miss our numerical keypad. While we wait for Microsoft or Apple to take up the designers with an OS-themed calculator, you can always add one of these USB add-on number pad/calculators for your budgeting tasks.
We actually reported about these over a year ago, but now they're available in red, white and black, the minimalist design made from recyclable ABS plastic and also happened to be winner of the 'Best Work Product of 2008", awarded by ID Magazine. Love the design, don't love the $83 price tag now that MoMA doesn't offer it for a nicer $58 like we once reported.
