One of the big annoyances with Windows is that it updates fairly often. At least once a week I would say.
But that seems pretty reasonable compared to the iPad.
Because the iPad doesn't do that much at all, you have to install Apps for pretty much everything, even the most basic of tasks (like adding up) requires an app installed. So pretty soon you will have a good selection installed. And they get updated often, very often.
Yesterday I was required to update 4 apps. Today I have switched it on and am asked to update a further 2. While typing this in has made the update noise again (even though I have the sounds switched off!!!!!) to let me know there are now 3 to update! Stop it!
