I prefer working at home behind my desk at my room. I have much more energy and organization there. Ofcourse sidejobs like checkups and followingups or browsing some quick sideinformation (wich is moslty important enough to proceed with what i am doing) I do that on the bus or train and when On my cellphone or even on my laptop if I decided to take it along with me somewhere. But yeah my desk is my deathzone :) I use my desktop and at my desktop I am the most productive. More then from behind my laptop or smarthphone.
