While mathletes, scientists, coders, and statisticians will appreciate Windows 7's built-in calculator's programmer, statistics, and scientific modes, everyday people will love figuring out things like hourly wages and mortgage payments without a spreadsheet. Yes, it may seem ridiculous to give more than a few lines of attention to something as minor as a calculator, but until you've seen the built-in calculator in the Windows 7 Preview, you've haven't known pure calculator bliss. This default calculator goes above and beyond the brick on your desk by including unit conversions, date calculations, and a neat new set of "templates" that let you do things like figure out gas mileage, hourly wages, mortgage payments, leases, and more. Check out some of the calculator goodness in the Windows 7 Preview.
Use the Mode drop-down menu to switch between scientific, statistics, and programmer mode. Those are all exactly what you'd expect.
