Apps, versus a competent browswer.
It is a known fact that Apple has the most amount of apps available for their iOS devices. It is also a known fact that RIM has a minute amount of apps for their BBOS devices, even lesser on their PlayBook.
Some PlayBook owners may argue that when you have a competent browser, the need for apps are greatly reduced, especially with the advent of html5 and the support of flash on the PlayBook. But I really don’t think thats the case, especially in a mobile device.
