Google and Microsoft are trampling all over each other’s territory lately. If it’s not Microsoft trying to creep up on Google with its search engine Bing, it’s Google offering word processing and other productivity software.

This week, it seems the line between the two has got a whole lot fuzzier. Google is talking about operating systems, and Chrome netbooks. Microsoft is now talking about a web-based version of Office.

Good thing? Bad thing? Competition is usually a good thing but we’ll have to wait and see how these new ventures pan out.
