I've learned to enjoy working on small screens. I did it because I traveled and didn't want anything I can't put in a backpack. For a long time I also used old low-res netbooks, because I didn't want to worry about a pricier laptop getting damaged (and because there was always one around). At one time switching to 1280x800 was a step-up; can't remember what resolution I used before then.

I know that there are way more people who are into large displays, and that's perfectly understandable, but I'll mention what the advantages of small low-res screens are for me:

- cheap + small + light + energy efficient;

- task focus: I'm looking at one thing at a time. I realise that a lot of people want the opposite ability, but I cherish this constraint. If you have problems with attention, you might want to consider this;

- more structure and efficiency in how you switch tasks: switching tasks takes more work than simply moving your eyes, so I quickly learned that thinking about what the next step is not only helps me get to the necessary window without any discomfort, but also helps with work efficiency and focus;

- information efficiency: really most of these advantages are about focus: with a small screen most of the information I have in front of me is relevant to what I'm doing. If I had all my windows looking at me all the time, only [100/number of windows]% of that information would be relevant at any point in time.

Disadvantages: partner's laptop better for watching movies.
