App, short for application, as in software application... been around for YEARS :-)
Why do people think something new has been invented.
To me it's like going back in time having icons all over the place instead of a structured menu system. Once upon a time this was known as a desktop and we had desktop icons.
I have an iPhone and iPad, that's the great invention not the apps. Personally I think the apps are a pain in the backside and hate all the updates etc.
Apps are cool for games etc but I really don't get why you would download an app for a website instead of just using the website. Perhaps I'm getting too old for this... hehe.
Using the standard web browser on the iPhone and iPad is where it's at for me.
