We live in this age for some time now already, but 'till recently it was only "why the hell does this software need to connect to the Internet". On-line document editing, on-line spreadsheets, on-line 3D modelling, on-line recipes, on-line weight tracking, on-line todo lists... Store everything in the cloud, use everything through the browser. So now I don't own any data nor can I easily export it, can't integrate tools with each other and have to choose my tools out of sea of unfinished, half-assed apps (also known as MVPs) that stop being supported or just disappear when developers get acquihired or just move to another project out of boredom.
Leave my files to me, give me off-line tools and a working sync. I just want Emacs to work on my tablet, and some sane way to seamlessly sync data between it and my desktop. Or personal cloud. Or whatever. And then I won't need all those fancy todo, note-taking and calendaring apps that all together can hardly beat org-mode.
Internet is not electricity, it's not always on and not always free. Until someone figures out how to put Internet into a bucket to use as a battery, please let me work off-line when I want.
