Buying software for your computer is becoming more like buying apps for smartphones. Apple and Google have recently launched app stores that let users either download programs to their PC or run in their Web browser.

The Wall Street Journal's Katie Boehret says this makes buying software much easier.

"In the past, you had to go out and get disks of these programs and install those and get the program that way on your computer," she said. "But this is a really great new way of installing programs without having to go to the store or buy a physical disk."

The apps range in price from free to as much as $80.
