Recently I decided to try Mailbox again. I had initially dismissed the app, probably partly due to the hype and partly due to the fact it messed with my folders, created new ones, and starred things without me wanting it to, however recently I have been spending more and more time using my iPad, plus I have seen a couple of colleagues using it.
As a stand alone app I have really gotten to like Mailbox’s deferral system. I am quite often on the road, or in meetings, so I found it really helped my keeping to a zero inbox. I do have a concern that from a GTD purists point of view I am just creating another Inbox with the deferred items, however the fact they pop back into my email, which is ultimately my main influx of information and hence drives inbound tasks, is incredibly useful. It acts as a pretty good reminder system for things I don’t really know what will happen yet, so maybe aren’t ready to be made into tasks.
