It’s amazing how many people complain about the hardware specs, but forget about the software. The iPad has the most important feature of all: usability.
Remember mobile internet before the iPhone? Nobody used it. Then along came the iPhone: technically nothing new: touch screens existed before, mobile browsers existed before.
But only the usability of the iPhone has made people start to use mobile internet. So much so that AT&T has a hard time keeping up.
Hardware features don’t matter if the usability isn’t there. And that’s where the iPad shines, just look at some of the video’s here: New Multi-touch Interactions on the Apple iPad. Again, it’s all about the software. Software is the key to ease of use. Apple has just made computing a lot easier.
