Presently, iPad is the tablet king. Android apps are at least a year behind Apple in maturation. Its likely that Windows will be 2 years behind, particularly if LibreOffice beats Microsoft to release. It is unclear whether MSFT will make a fast comeback or do a Vista thereby retarding adoption. Personally, Win8 does not wow me with its Metro Interface ... essentially live apps on a sliding desktop. Perhaps when Windows is designed into an office furniture, then perhaps it will catch on.
