Debating which I should get - can save a little money by going with the iPad with the smart keyboard cover - but will it really do everything I need? Don't have to do anything with specific programs - use Pages/Numbers/Keynote currently and don't see any need for other programs in the near future. Do use web extensively - database website queries etc. I've had an iPad for years so very comfortable with them. Any advice suggestions? And if I do go with Macbook Air - would probably wait a month or so to see if they do come out with a refresh.
