I'm not an "if apple makes it, its the best" type person, but i will address these points:
1) Its not a netbook, and in fact, at the keynote, Jobs explained why its not. I don't own a netbook (my wife has a dell mini) but I now use my ipad for 95% of the things I used my laptop for (I'm typing this post from my iPad). As far as not being able to save files? MANY apps have the ability to save files, just not in a folder on the "desktop". I use Office Pro daily at work, and i currently have 22 word files saved in it.
2) I have a Motorola Droid. With an app and some work, its now a wifi hot spot. There are several phones that have this functionality built in (Verizon's version of the palm pre, for example). I will agree though, that having that capability made the iPad far more productive for me as I can now use it throughout the day at work.
3) You used Facebook apps in your argument for Flash. Enough said.
