As mentioned in another thread on Flash, I my reason for buying the iPad was to use as an instant on web device that could sit on the coffee table and had a long battery life.
I am generally happy with it but there are (naturally) some disappointments.
1. I can't print documents. A fix is due soon but will require a compatible printer.
2. Saving email attachments is problematic. There are 3rd party solutions but this should be native functionality.
3. Not Flash compatible. I wouldn't care about this except that it means that I can't access some web sites.
4. No cursor keys. The magnifying glass thingy is cute but quite fiddly. Selecting a block of text is quite difficult
