I'm stand corrected, 21". Still tiny. You can sit at your desk all you want, normal people watch tv, movies etc. and do it sitting in there favorite chair. If you spent 1/10th on your monitor as I spent on my TV, you have a crappy monitor.
If you had a larger screen you would know there is a noticable difference in 480p(HD wannabe), 720p(almost there) and 1080p(full HD)
