Interesting idea. I certainly cut down last year on app switching and I feel happier for it, but that may just be because I spent some time settling down on the Mac platform.
Most my choices are now the default ones, with only 2Do standing out. To be honest, I’ve been getting annoyed with that app not seeming to be able to sync with the reminders app reliably, so with this post I’m abandoning ship there too. Similarly, I did return to Fantastical for a bit this year, but again it was just not as reliable as the built in Calendar app (repeating appointments, mainly). And I tried out Drafts, but that was mainly because I was interested in the scripting possibilities. Gave me 10 days of fun, so that’s fine.
Anyway, I’m in.
I’m going to try sticking with the built-in apps for my mundane tasks, and probably keep my specialised apps constant unless something comes along that lets me do something new.
I use Xcode, Graphic, Pixelmator, Logic, Final Cut, PDF Expert, BBedit and smaller utilities along with the default apps.
My phone and iPad apps are chosen to complement the Mac, so no need to worry about them independently.
