Chrome uses webkit, which is open source and is used by safari and iphones, and androids too I believe.

Webkit is opensource and is rapidly evolving; it's basically pushing the edge of what the web can do.

Totally different from IE. A closed, old, non-standard browser only used by people not savvy enough to know what a browser is, and most importantly, it's holding the web back.

I believe chrome is fairly standards-compliant, which IE is not. So your app will be more portable.

I don't like "webapps" in general. I prefer command-line programs
