Firstly the good thing about the iPad 2.0 (which PCs have been able to do for almost 30 years) - Now you can plug a cable into the iPad 2.0 and display whatever is on the iPad 2.0's screen onto another device like a TV or data projector, not just videos and photos as you can with iPad 1.0. So if you are teaching an iPad app in the classroom, now you can display it on your projector (if you have an iPad 2.0).

For those of us with wireless iPad version 1.0 (me) the latest release of the iOS which is now at version 4.3 allows you to use a 3G device (my iPhone 3GS did the trick) to act as a local wifi hotspot. I was able to tether my iPad and iPod touch to the phone using bluetooth and access the Internet and mail from the iPad.

People in the vicinity can't randomly access your personal hotspot.

With this update it means that you really only need one 3G sim card and therefore one data plan. Something to consider if you have an iPhone and are considering buying an iPad. Was it fast? Certainly was.
