Minimalist's computer

"What I have found is that the iPad has in fact become what I have come to think of as my everywhere else machine. In other words, when I am sitting at my desk, in my home office, I use my Macbook. Everywhere else, the living room, the den, at a client, at a coffee shop — I use the iPad. This means I use it quite a lot but there are certainly some things I wait to do on my Macbook (web development stuff for instance). That said, this is more a limit of available apps then the iPad itself. Most of what I do, which constitutes writing, browsing, social networks, and email, can easily be done on the iPad (and in some cases it's even better). My Macbook rarely leaves the desk."

I have to agree with this quote that most people don't need a PC or laptop which requires you to sit down on a desk to use for the 90+% of their day to day needs. All you need a something similar to an iPAD.

Walt Mossberg also said that 80% of user's computer's need can be done in an iPad.
