Google Chrome is a new web browser from Google. It's lean and lightweight, all the stuff we loved when Firefox first came out taking over the Mozilla suite. Initial reaction seems to be "why?". Of course, the first thought is Google's browser gives them the ability to log EVERYTHING we do for their stats and ads, but on the lighter side, they've given us a bit of a one-click way to access the Google Apps like we would any other app... less of the "web-browser" experience. It's a neat feature, sure it'll be useful for alot of people.
Google Chrome is Windows only and doesn't really give me any reason to drop my current web browser. Though I'm happy some new innovations are being considered and I hope this triggers innovations elsewhere as new versions of Firefox and Internet Explorer are released.
