Lets put things into perspective here...
The tablet is not a laptop, it can perform many functions of a laptop, but it is truly not one.
It does have a place in the field. I have found that for business, being able to show information instantly to partners without having to 'boot up' or 'plug in' is essential when I want to get a point across.
It is great for email, messaging, movies, light surfing, reading, and even playing some good casual games on.
The dock makes it appear to be more like a laptop, but again.. go back to my 2nd sentence, and do not put it in a category it does not belong in.
If I need to develop, I use my Alienware mx17-r2, if I need to demo products I have my Inspiron. If I need to take notes, read a quick email, show a slide deck / video, or just look something up real quick, I have my TF101.
So this is more about how you set your expectations above what a product is intended to do, and now have buyer's remorse because of it.
