Try using a MATTE screen protector. It cuts down greasy prints by 80-90%.
I have stopped carrying a laptop since buying my iPad. Its instant on, consumers less power, a great e-reader, photo viewer and browses the net very nicely.
I use it in the following order of frequency
1. Document reader
2. Internet browsing
3. News reader via third party app
4. Watching video
5. Gaming
There are over 300,000 apps to download from the app store. That's where you will find something that will suit your lifestyle or requirements.
I will say wait for the iPad G2. The current iPad is lacking in RAM (nothing to do with the 16 / 32GB storage). It has 256mb of RAM whereas the iPhone4 has 512mb. If you open more than two or three web pages, the iPad will 'forget' the opened web pages and try to reload them when you return the page. If you are no longer connected to the internet (like in the crew bus trying to read GABI flight plans) you will find a blank page.
