Don’t think that wireless NFC tags are just for mobile payments. You can do practically anything with them if you know how to program them with small bits of data. Some free apps make this easy and I’m already on the NFC bandwagon at home.
2011 wasn’t really a year in which we saw a lot of big changes on the hardware front from Apple, even though iOS 5 and iCloud made big splashes in software. But I think we can expect a lot of device changes in 2012.
