Although this feature has been out for a while I thought I would remind you, if you have not yet done so to "switch on" mobile viewing for your google site.
It's really easy to do.
Click on more actions > manage >general > scroll down until you see the "automatically adjust site to mobile phones" check box, tick the box by clicking on it > remember to save your changes
I have seen sites that look better as desktop mode, but it all depends on your site.....
Let me know how you get on.
