Dual Nationality is wonderful (so far) from my experience. I was born here in the US, but my mother was born and raised in the UK. She became a citizen when I was 12, so we thought she was no longer a UK citizen. Since I'm moving to the UK to study/live this September, I was looking into visas and the like. Much to my surprise I found out I'm a British citizen as well, and that my mum is still a UK citizen too! I only found this out from the nice people at the Los Angeles Consulate and it made me so excited. I was in the UK about a month ago and going through the passport line fast was wonderful. Only thing that seemed a problem was the Immigration official coming back into the US didn't realize that US citizens can be dual nationals (the US gov't just has some stiff rules about using your US passport for entering and leaving the country). But othe than that it's great, I highly recommend it.
