Glad you are done with schoolyear, Axi, and that you'll be able to play more soon.
Indeed, Noobas, a 19 inches screen for a laptop is pretty big already. Actually YOU are making me jealous there.
As for my future monitor:
- it will stand on the desk (very large and solid desk, custom built by myself, no space issue at all: initially it was made for two 20 inches CRT monitors, two towers, a scanner and a printer, and a ton of papers and books)
- I'll sit on the chair in front of the desk, nothing special (my back could use a new chair though, I guess)
- the desk is large enough to allow me to position the screen at the best distance for me and even to possibly move it back if I wanted to watch full screen videos.
- I don't worry about built-in loudspeakers... they are just trash anyhow and I won't use them, so NO loudspeaker is perfect.
- What I'll do with it:
. of course regular stuff: word processing, desktop applications,...
. playing games: AO of course, other Online games (testing with AP in mind), real-time strategy games when a good one it out (doesn't happen often), not really FPS or just to have a look
. watching movies: I have a (relatively old now) TV for that but it would be really handy to use the PC too
. graphic applications, mostly things like the things I do for AP (web, wallpapers, etc); for professional-level colors control I have monitors at work, so I just need to be able to properly set the colors on the monitor (usually they come with awful settings) and have a good display but I don't need a Barco screen, or even an Eizo!

. I can always get a color calibration system from work to set my home monitor correctly.
