Apple kind of has an iron fist regarding its stuff. They recently forced Amazon to remove its direct link to the Kindle store from the Kindle app, as Amazon refused to pay Apple 30% commission, which is Amazon's profit from Kindle book purchases. They wanted everyone to purchase ebooks from their IBooks, which are more expensive and limited in selection. Amazon said screw 'em and removed the Kindle store. Again, there are work arounds.
The nice thing about IPad is there is no way you can ever get a virus or malware, Apple so tightly controls everything.
I love the portability and convenience. There are other net pads that allow Adobe, and Amazon plans to come out with one soon, if it's not already here. The apps available for IPad are amazing, I can watch HBO and ESPN with my current Directv subscription for free. The cookbook apps are amazing. I love it!
Again, it is an accessory, not meant to replace a laptop or PC. In fact, you need a machine in order to connect to ITunes and download your updates, etc.
