Seven mobile trends to watch in 2012

Arguing Apple vs Android and apps vs web is fun, but so 2011. So, thinking about 2012, a handful of mobile trends are worth tracking:

1. Transactions/Authentication (NFC , Square etc.)
2. External sensors and connected devices (Bluetooth 4.0/Internet of Things)
3. Voice (Siri vs Google)
4. Presence (Moving beyond check-ins)
5. Home Hub (Airplay, HDMI outputs, home controls)
6. Connected cars (3G-enabled, streaming Internet replacing AM/FM etc.)
7. 4G (Speed changes behavior)

I am collecting links on these and other mobile topics on Delicious.
