First, you should know that the so-called LED tvs, are not really LED tvs. They are LCD tvs, with white-light LEDs for a backlight. The LEDs replace the cold cathode fluorescent lamps (CCFL for short) in the tv, and should last a lot longer, use less power, and have the potential to give a much higher contrast ratio (because portions of the backlight can be selectively turned on and off, unlike CCFLs).
Other than that, they are the same as LCD TVs and have most of the same advantages and shortcomings. LCD TVs, even with CCFLs, are great, and I have no qualms recommending one, so long as you buy a good brand.

It's pretty good, but don't buy one until the 2nd or 3rd generation of the technology. I saw the 1st generation at a store and motion blur is evident. The LEDs aren't turning completely on and off fast enough, and it's really noticeable. I've read the later generations will fix this.

My Phillips TV does not play music DVD's. Why not? Driving me crazy. All other DVD's play perfectly and the region is ok.

very well put, the LED backlights use several thousand white led's that are in small clusters of 5 or 6 - when a cluster fails you will never notice.
The backlight clusters are also adjusted with the brightness to improve the contrast levels in some sets this can cause a "halo" effect on dark screens but a menu adjustment removes this

Thanks for the comments. I remember you commenting on the halo effect before, and I was hoping you'd chime in with that again because I haven't seen this problem.

on a dark picture anything bright (car headlights, lightning etc.) would make the set drive that area of the backlight at a much higher level, as the led clusters are a fixed shape the surrounding area then "glowed" and was very annoying - most mfg's have changed the software to reduce this problem
- anything improved will have something for people to complain about, I'm just happy when my set works -
