It works for me too. I know that the concept of which format is "good enought" is a very subjective matter, but in my opinion 720p is in a very good sweet spot and there is not much extra benefit in going 1080p. I mean that the jump from non-hd to 720p is a huge jump, it is the differense between a "insufferable blurry mess" and "very sharp", but the difference between 720p and 1080p is more like "very sharp" to "a tiny bit sharper". I'm not saying that 1080p is not nice, just that it is not indipensable.
But then, my disdaing for 1080p may be just result of the fact that I'm not used to it. After all, up until a month ago my internet was way too slow for any kind of HD video. Lets see how I feel about it after 6 months with an OK internet.
