I find them terribly constricting. If you don't conform to the constraints that are forced upon you by the ecosystem and the device then you are at the mercy of the ecosystem and the device and this is nothing but bad news when you hit a problem or need to do something free-form. I too used Google Calendar, but it's terribly complicated to enter an event in on an Android device accurately, the web interface is clunky and the sync isn't reliable if you're in a poor reception area. Same with evernote and any notetaking software (google keep as well). It's impossible to take notes on the fly quickly without observing the device otherwise you end up listing garbage and missing the stuff going on in front of you. Then occasionally you might find a picture says a thousand words - which you're instantly stuffed with. Your focus is 80% on the machine and 20% on the problem when notetaking on a computer of any description. I carry a little notebook (3 for £1 in Tiger here in the UK) and a mechanical pencil (doesn't need sharpening and has a rubber - Rotring Tikky box of 10 for £11.99 on ebay) for notetaking. As for scheduling, I know what is when (don't underestimate the power of thinking about this rather than contracting it out) and for navigation, I'll scribble out a diagram before I leave of where I'm going. Gotta use that geography GCSE for something. And no you can't disable everything unproductive on a smartphone. I tried it and my device slowly switched all the features back on again. I decided that the following process should apply: 1. Start with what you need. 2. Add what you want. Point 1 turned out to be a dumbphone (calls and SMS) and 2 never materialised.
