Lots of people were turning up at Google Summit workshops with an iPad, only to be disappointed that many things that work on a computer either don't work at all on an iPad, or work very differently.
Although they have many advantages, its useful to remember that an iPad is not the same as a conventional computer. Many of the things that one can do on a laptop are definitely not the same experience on an iPad. It can be a little frustrating!
Google tools have typically been designed to run in a web browser and aim to be device-agnostic, but that ideal does not always translate well into an iPad experience. The best experience on an iPad is when you use purpose built apps, and with the right apps it is quite possible to live comfortably in a Google world on an iPad.
