I had a similar realization today. I purchased a keyboard cover for my iPad mini. That taught me two things: that I loved watching video, using social media, and writing with it more than I thought I did, and that to really take advantage of it, I’d need a bigger iPad.
I’m a photographer, among other things, and work with media constantly, so there’s definitely a big portion of my work that has to be done on a desktop (not even a laptop cuts it sometimes), but the cases where that’s true are increasingly slim. It’s always that last step. The final edit. Mobile/tablets stop just short of the finish line in some workflows.
Using a tablet gives a nice sense of focus though, which I especially appreciate when writing.
