I love NFC. In fact, I use it every single day and can't imagine going back to life without it. Since I'm running CyanogenMod 10 on both my tablet and phone, I take full advantage of the profiles feature, which allows custom settings for various situations like work, home, night, and more, each of which can be activated (and de-activated) via NFC.
Beginning now, Samsung owners with NFC-capable phones can utilize a very similar feature with the newly updated TecTile app. For those who may not know, TecTile is a Samsung proprietary application that lets users write and re-write activities to NFC tags.
