I live without internet at home now. It's amazing how much more space there is in my brain after reducing that single input.
It's actually fine for that. I have 24 hour access to my uni building so I just go in when no-one else is around to write my code.
I print off research papers to read them at home/coffee shops. I prefer reading from paper anyway.
Got my phone if I really need to read something. But limited data allowance, so have to ration it...
Of course, nothing beats Google, but if the docs are good (big if) you tend get a deeper understanding of your tools.
