I have an iPhone 4 and an older Macbook, and I was trying to decide between getting an iPad and trading in my Macbook for a Macbook Air. I decided on the MBA because it has a full keyboard, and because Lion is supposedly bringing iOS style improvements to OSX. So how does the Mac App Store compare to the App Store for iOS? Am I going to be missing out on a lot of iPad specific apps, or will the iPhone and MBA cover most things? Also, overall is it just a different way to sell the same software, or are there a lot of unique apps for it?
