Some apps will come with a small subscription fee (such as the NYT, which will also be available to read offline), a one-time download fee, or even free.
If you're a big fan of apps on your mobile phone (and who isn't?), then Google is betting you'll dig its newly announced Chrome Web Store, which brings apps and games to your web browser. Similar to iTunes or the Android App Market, developers will be able to build apps to sell through the Chrome Web store across various platforms — Mac, Windows, Linux, along with a number of different browsers (you don't have to use Chrome to access the store) — that will be accessible in 40 different languages in 70 countries to start. The apps are downloaded directly to your browser (like a "super bookmark"), which eliminates problems you'll find when building applications for different operating systems.
What kind of apps can you download? Well, if Plants vs. Zombies is one of your addictions, you can download that, or you can play LEGO Star Wars on your home computer. Can't argue with that. Look for the Chrome Web Store's grand opening later this year.
