My last two telly's have been Ambilight and it's one of the reasons I'd always include Philips when considering a new one.
For the first week or two you (or more likely your misses) may find it a little distracting but rather than an irritation it's more a case of "Oooo look, the pretty colours on the wall...
...and they're the same as what's on the box!". As long as you haven't got it cranked up to 'Disco' then it very quickly just becomes part of a generally more relaxed visual experience, indeed giving a hitherto absent ambience to your room.
After a short while (if you leave it on permanently) you almost won't notice it until some airhead - sorry Dear - presses the wrong button on the remote and all of a sudden it's like someone's turned the lights out - which I know they have but you know what I mean.
As you can tell I'm a fan
