Google having their own browser is a move I did not anticipate and is actually a brilliant idea in terms of os replacement for other proprietary operating systems, hence Microsoft. I think it will actually be very successful for two reasons:
– being open source
– is powered by a web state of mind (and no one is such as google is)
The fact it is open source I think means a killer for IE since having one proprietary browser and one open-source (Mozilla) is one thing. Having two major players with an open-source browser and one proprietary means the proprietary is bad.
As for myself, I think it means a big change in terms of web-based application and their bright future to become the dominant development platform for new products and services. I find it hard to rationalize now developing platform-specific applications while the ability to cross-platform them is so easy.
Anyway, I am very glad about this. As for chrome, I played with that a bit this morning and after a while, it stuck my laptop but I guess this is only early-stage problems.
