I actually think NFC is an awesome feature, but just hasn't caught on due to marketing and companies not willing to spend dosh to join on board.
When apple joins the wagon, it will catch on because market things in an awesome way to both consumers and companies, which will be good for android users as well.
I just bought a few nfc tags myself and they are awesome to use.
I have one near my front door called " going to work" which turns off wifi, puts power saving mode on, switching on my music etc all with a single tap of the NFC tag.
Then I have a sticker on my works computer which is called "at work" which switches on wifi, turns off music, puts my volume on a low setting etc all with a single tap as well. This is normally what I did anyway when I had an iPhone, but now I don't need to flick through settings and buttons, I just need to set it up once and then just tap. Awesome
