Have you ever realised that everything that google makes: Google Search (the obvius one), google chrome, google sketchup(I love it!), Mail, imag... is so simple.
The Search with classic home is just a white page with links above the top and the logo with search in the middle. Easy to understand and easy to use!
And that is why I can't wait for the new chrome OS coming out in january(if I remember correctly!). The first version may not be so good but after a bit, google will jump off and its new product will start competing with Microsoft and Apple.
The nice thing I like about what I hear about the new Chrome OS is that it is going to be based on Unix(Linux is based on Unix) and it will become open source. Which may give Microsoft the ability to copy it but, one there will always be copying, two It will shine it up anyway and three, people will probably stick to Google at that stage anyway!
Google has a lot of things on the go, chrome, wave, etc. and it's working in a very clever way becoming a big company. It will be interesting to see what kind of choises it will make in the future!
