I'm with you on Google Apps. It's a good product but it is very limited and doesn't have the look and feel of modern apps. I don't like using Gmail either. It's unnecessarily quirky and busy. Google doesn't make things as fun to use or as easy to use as they could.
I think that the Chromebook model is better than it seems. Only problem is is that businesses are struggling to adapt to it. But it is a business problem and failing, not a Google one. Google supplies the tools, business can't grok them.
In the same vein, the Linux world has everything businesses need and have for a decade or more and yet almost no businesses have cares to go down the 100% Linux path regardless of the massive savings and ease of use once the transition is over.
