^^Agreed. My laptop now stays in my office, unless I know that I will have to do some blogging in the evening, or if I know that there is a big story or news breaking in the real-estate world.
Due to leaving my laptop at the office, over the past three months I have only had to make three late night trips back to the office, because my iPad could not handle what I was doing.
Much like @Brent, I use it everywhere... from airplanes, to trains, to walking down the street... even last night, I was doing some work with a cigar and a scotch on my patio, where I would have rarely taken my laptop.
