Nice! It's great to see the entrepreneurial virus run across the earth to every country like this. Chandoo is a nice business and I am sure you can adapt it to the new tools that emerge after Excel. Won't there always be a need for some sort of tabulator like Excel? Do Google docs accept most of the same formulas and charting logic from the most advanced worksheets?
Google docs, zoho and office web apps provide most of Excel's basic functionality. I am sure they will evolve to be more usable, functional during next 5 years.
