A16Z Benedict Evans says phone is killing both desktop and tablet, and I am just trying to get an idea of relative percentages to see if this is true.
The Smart Phone isn't killing the desktop, and more then the desktop killed the main frame, we still use powerful dedicated computer clusters for computing, just like we did in the 60's and 70's before the desktop. The desktop just expanded the market of people who own computers, much like the smart phone is doing now.
That being said I do most my reading on a desktop.
Around Jan-Feb 2013 I read the whole ASOIAF (i.e. Game Of Thrones) series on an iPhone 4, since then I prefer it to laptop or paper, I probably average a book a week. IMO if you're willing to spend money on apps the only real limitation of mobile is input. Output if fine if you have good eyesight.
I am just intrigued about this whole "tablets replacing desktops" thing, and I am trying to get a sense of what other people use.
For developers like me (and you?), a tablet could never replace a powerful computer. But for average users, the tables can do most of what a desktop does (email, netflix, facebook, etc.)
