"Google Docs is less feature rich than Microsoft Office"
--Based on my limited experience with brower based exiting of Google Docs spreadsheets verses Excel.... That would be an ummmmmmmmm..... Understatement.
"offline is a problem"
--Perhaps the more appropirate statement would be "not possible" don't you think?
I'm as happy as the next guy that someone is challenging M$ and thus forcing innovation (e.g.: Amazing how much better IE has started getting again after the period of non-competitive stagnation). Similarly, I understand the cloud is a paradygm shift and that the associated toools will improve/evolve. However, the simplistic tool that is Google Doc's spreadsheets is so limited as to be laughable for complicated spreadsheets. (Or is the "paid" Google version just that much more feature rich?) Here's a very simple example: "Paste Special - Formulas" - You have "Paste Values" and "Paste Format," but no Paste Formulas??? To me that is a glaringly obvious lack that should never have been left out in the first place.
Fortunately, it will probably improve over time.
