Focus is key in getting stuff done. Assigning equipment for a given function allows you create time and space for completing tasks.
Here is what I suggest:
– Use your computer for creating content. This includes doing task specific web research related to content creation.
– Read, watch videos and generally surf the Internet on your tablet. Use an RSS feed reader to collate news from your favourite websites in one place.
– Write and check emails / social media responses on your phone.
To increase productivity even more assign specific environments for using each of the above devices e.g computer/office, tablet/couch and phone/desk.
