If I had a laptop, I'd probably still sit at home and type.
For me, writing is divided into two parts. Generating material and putting it on paper.
Now, coming up with the ideas is where I just observe everything. I usually get quieter and just look at things, observe how people talk, mannerisms, etc. I make connections to a possible situation if I have one, and get a small idea worked out. The I build on the characters. Their traits usually write the rest of the story or at least a huge part of it.
Then, I take the rough idea, sit down in front of Microsoft Word and type like a madman. The ideas freeflow out, and then I edit that draft.
Just yesterday I had a burst of inspiration and I kicked out somewhere like 20 pages. It was over a few hours, but it was worth it. My story is really piecing together, and few feelings can top that.
