zod96,
Many people (myself included) who want a larger, non-TN screen wind up getting a 32" 1080p TV. I bought one with an IPS panel a couple years ago for $380. At the time that was the same price as the Dell 2408WFP.
I bought a 2408WFP and used it for a few months, but I felt that I couldn't get close enough to it for it to be immersive for gaming (closer than 2' away caused eye strain, and 2' away was not immersive). I sold it at a small loss to buy the 32" TV, and I've been very happy with that purchase for about 2 years now.
Some people still like to sit really close to their 32" TV, but I think 3' to 3.5' is the best viewing distance. I say that because many people do not have a desk that can accommodate that viewing distance.
The decision also depends on the usage of the screen. I bought mine primarily as a gaming monitor. And as a gaming monitor, I would not say that my 32" 1080p TV was a downgrade over the 2408WFP that I used to have. However, with a lower DPI, it will obviously be less crisp for normal office usage and will have less screen real estate than a 2560x1440 monitor.
For me, I actually prefer the lower resolution for gaming, because it allows me to run at the native resolution with a less-expensive video card. Also, at the time the least-expensive 27" non-TN computer monitor was $700, which was completely out of my budget.
