A friend of mine has this type of headlights on his BMW, and while they are very cool at night with the adaptive beams that light the road without blinding other drivers, I can't say that I find them to be a must-have, and I'd be hard-pressed to pay the premium to get them on my car compared to my current xenon lights that can only corner as I turn the wheel.
Unless you're frequently driving at night, you'll be just fine with halogen or xenon lights.
Is blinding that big a problem? Assuming the lowbeams are well adjusted, they should never blind anyone. The number of times each winter that I forget to switch off my high beams for an oncoming driver and blind him is between zero and one.
It is to me, but my vision at night isn't the greatest. I see quite a few people with HID/LED lights now and the blue shifted spectrum and poor aiming have caused me problems.
So I paid around $2k for mine. Most people thought I was crazy. But, living at the time in an area with a lot of dark, wooded roads as well as what seemed to me to be an extreme deer overpopulation, I don't regret it one bit.
