Impending iOS4.2 for Ipad: 4.2 random thoughts

The web is abuzz with the impending release of this long overdue update to the Ipad. Having been long accustomed to features such as multitasking and folders on the iPhone, the limitations of iOS 3.2 has become painfully obvious and unbearable.

(1)Will the apple server crash from the sheer demand of 10 million iPad users downloading the os at the same time?

(2) What apps that I hardly use (and deleted to make space for new apps) will i have to download again from the app store now that I have folders?

(3) Which of my ipad apps are going to crash because the app developer did not work on an update for iOS4.2?

(4) Will I lose the wonderful screen rotation lock button becos Steve Jobs prefers a mute button?

(4.2) Why did we spend $9.99 on a printing app just a couple of months ago only for apple to include airprint for free now (not that I am complaining)?
