Like most of us (I assume) I am devouring everything I can about the iPad - from all viewpoints. Frankly, for me, I cannot wait to BUY one sight unseen! Sign me up for the 16GIG WIFI one - that would be perfect for what I intend using it for. IN FACT, I may go so far as to get 2 - one for my 84 year old father who is a bit fed-up with sitting down at his computer station but doesn't want to deal with a laptop.
Of course there are shortcomings - there always are shortcomings with any 1.0 released product. During the process of launching the item someone will always identify a change that will have to be pushed back a back to a later release. That is the nature of all things - especially in the software and technology world.
The question you have to ask yourself is, for how you intend on using this device, are those items really "shortcomings"?
