Tablet PC problem statement

Dear folks,

with the advent of portable computers which became so-called laptops, they even went further to become tablet PC and computer pads using the touch screens. We can see or more exacly foresee that these computers will evolve in very interesting tools to improve interactivity during presentations. 

Here is the problem:

During presentations, at the moment, in class, you have to turn your back on people in order to write on the board all these questions and comments. It takes a long time to draw those sketches. So people started to show some presentations but all information was shown and students did not have to take any notes. They just had to wait until the teacher gave them the presentations. Then, why bother coming to class ? Students never had to make the necessary effort to concentrate and write down notes during class. This means poorer learning. 

The real effective approach there would be to come with a complete written presentation (the lecturer's powerpoint) printed on paper with all comments. This would not be given to students. Then, the presentation on the computer would be a stripped down one where only the images and tables are shown. Then, the lecturer would simply annotate these during class using the touch screen.

The advantages would be that :

1- the lecturer never never shows his back to the students. He can keep constant eye contact with them. 

2- Students have to take notes by themselves and revise them later with the stripped down powerpoints. 

3- These limited presentations, given to students, force them to complete them with their class notes and also with reading through the textbooks or on-line information. 

What is needed now: 

I am a looking for a portable computer (laptop, tablet, etc) with a touch screen, which allows me to make interactive presentations based on skeleton powerpoints. These powerpoints include only the images, tables, etc. 

This means that it should be connectable to a projector through a VGA connector.

This also means that I need some link allowing to transfer the powerpoint files made with Libre Office or Open Office.

Well, I guess after these few years have passed, you're needs have been answered with the huge amount of tablets that now flood the market place with the functions you need. That includes a VGA connector - Adapter.

Well, the Apple Ipad are not that good and I have found the way to solve their parasite cliking habit. Still, the best is to proceed with a reversible laptop like those Lenovo Fex. Most other professors kept their Toshiba laptops having better touch screens not proceeding with unwanted clicks. Question : are the piezo based touch screens better then the capacitive ones ?
