They say nfc use for payments and stuff. But really for me it's all sales talk atm coz it is not yet mainstream.

For me personally I find it very useful though. Here are my usage:
1. As automation. When I enter car. Tap dock. Car mode on. Gps on. Waze on. After finish driving. Tap dock. Car mode off. Gps off. Waze off. I safe about 30 secs every drive coz no need to fiddle with phone.
2. I have a nfc tag on my ipad. When I want to tether from ipad to phone I tap phone on nfc tag. Automatic Tether auto on. Tap phone again on tag, tether off. So no need to fiddle on both gadgets. Just turn wifi on ipad and u good to go.

Nfc is part of my life now.

S3 and ipad owner. S3 no lag. The transition thing is adjustable. By default is set to 1.if u want faster set to 0.5.or even faster set to 0. 0 is no transition affect, just bam!

Btw, Just to note the sms and contacts apps have a bit of lag  When opening . I updated to jellybean and it's improved. But still can't beat iphone . But tolerable.
