I have the 24" (2407WFP) Dell you mention.
It’s beyond awesomeness.
I went from a 21" CRT (an old graphics design monitor… Weighs somewhere in the area of 80+ pounds) that I was running at 1600x1200. When I was looking, I realized I didn’t want to move to a smaller resolution, so I took the plunge, and this is the most happy I’ve been with any of my computer-related purchases ever.
Many would say that a dual screen setup is a better choice, and for many, it is. Personally, I can’t stand two screens. I’m always losing my cursor, and I have to look at the other screen if there’s something I want. The widescreen lets me do that all on one screen. (it’s not a problem to have 2 webpages side by side.)
Even after I got the 24 inch, I was running dual screens alongside the 21" CRT, and I found that I simply didn’t use the second screen (Though it did give me well over 32 inches of workspace measured horizontally) The 21" has now become my monitor at work, and it’s on its’ last legs.
I also love it for watching movies. 1920x1200 is better than 1080p resolution, so watching something like the shuttle launches is great. It even beats out the 37" LG LCD my parents own (which only does 720p and cost more) It’s great because it can double as an HDTV… And with all the inputs, you don’t need to screw around with cables or anything.
Oh, and it’s got a card reader and USB2 hub built in (when I made my computer, I didn’t realize until after that I needed more USB ports and how nice a card reader would be to have)
I’ve liked it so much that when I bought my laptop I made sure I was looking only for widescreens. (I ended up with a Gateway CX2724 tablet, which is awesomeness as well)
You also have some other options. If you’re looking for something a little less pc, Apple makes a 23" Cinema display for about $1000USD. It does 1920x1200, and it’s nice looking to boot.
They also have a 30" Cinema display that does and astounding 2560x1600… Of course it’s $3300USD. It’s probably the nicest monitor I’ve seen in person. I’m not a Mac fanboy by any means, but damn, I want one. And if $3300 is too expensive for you, their refurbished site is selling them nearly half price (and yes, they’ll both work on a PC… 'Course for the 30" to run at full screen you better have a decent video card)
