Google has just announced that it's making the Chrome Web Store available to the "entire userbase of Chrome" -- all 160 million, according to the company's latest numbers -- and in 41 different languages no less, although those outside the current markets will apparently only have access to free apps initially. What's more, it's also now added in-app purchases to the mix -- which it notes developers can add to their apps with "literally one line of code" -- and it's announced that it plans to "keep it simple" by simply charging developers a flat five percent fee instead of opting for some of the more complicated fee structures out there. As for how the Web Store has been doing so far, Google revealed that there has been 17 million app installs to date, although it provided few details beyond that.
