i was going to buy the samsung 204b, thank god best buy did not have it in stock, it turned out to be a blessing in disguise as I ended up with the viewsonic vp2030b, this is at 1600x1200, it DOES seem wide. but the only reason i didnt go wide screen is because I use a tablet with my computer and it wouldnt scale properly to the widescreen.
as long as you dont plan to have dual monitors, or already own a non-widescreen tablet, go for a widescreen monitor, they're the best for movies.
