If only Dell would make one with USB3 and built-in speakers, I feel like they would give the TBD a run for the money.
Thank god they don't, IMHO. If your going to buy an IPS or e-IPS panel, chances are you have a great speaker set, etc. No monitor speaker is going to match a 2.1 or 2 or even a good pair of headphones.
In any case, the 2142M is a great entry level IPS from Dell. It is E-IPS, which means it is not true 8bit IPS but instead is 6bit. That said, the screen looks amazing and has no noticeable ghosting in games IMHO. The best thing about Dell monitors is they are really ergonomic. You can flip them vertical, tilt, swivel, etc.

I've enjoyed the
Dell U2410. Dell displays sometimes get snubbed by monitor snobs but my original carried a 3 year warranty. When it died, Dell gave me this U2410.
True monitor snobs go for Dell, HP, or Apple; with the first two being the high end models since the Apple TBD is already a high end model (in terms of price and quality). There is so much misinformation on monitors out there, esp. since the industry is shifting to poorly made panels on poorly designed frames, because that is what the consumer wants (aka 16:9 so I can play my Xbox, woo!).
In any case, Dells are the de facto standard for a value IPS outside of the 1,000 dollar range for Apple, HP, and Dell high-end IPS panels.
), but they are offering a $20 rebate. Has DVI, VGA and HDMI.
