It is no secret in the Apple tech community that people are dumping their MacBooks and working solely on the iPad. Federico Viticci writes solely on his iPad and has several guides on how to do great things with iPad.
I have been writing about Apple in some form or another for the past two years. Starting as an app blog for non-traditional students, to moving my work over to The Apple Fancast, then back to my blog.
I've had this thing running just a fraction of the time of other indie blogs and that's because I didn't get my first Apple device until October of 2013.
