I use my iPad less frequently than the author of this article. I use a combination of my Macbook Air 11" and my Nexus S. It works fine for me.
The only things I ever use my iPad for are games and air travel. I rarely check my email on my computer anymore, so good is the experience on my Phone.
The problem I have with this article is that I suspect that the author would feel the same if he had an iPad, but he wouldn't have written this article.
Why? My iPhone and MacBook (per iTunes) can stream to my Apple TV. Besides that, I can access all media on my MacBook or iTunes Match directly from the Apple TV.
We barely use our iPad. My SO sometimes takes the iPad with her when travelling, because it is lighter than her MacBook. Other than that, I charge it once per month to keep the electrons flowing.
I check my email on my phone. For most of the emails I send, the phone is also sufficient. If I need to send something longer than this comment, I will switch to my MacBook Air. Honestly, it's no more of a hassle than pulling out the iPad and it has a keyboard.
