Other than the obvious texting, browsing, and you know, using it as a phone (haha) I use my phone as my "iPod" with the Google Play Music app. It's very useful to have all of my music synced on the Google servers and to stream whatever I want Whenever I want.
Let's see, what else do I use it for....
- Flashlight using the LED and a flashlight app
- Netflix Streaming when away from home
- Used Google wallet for a little while, at least until I broke it on my phone and the novelty wore off.
- Work and personal email
- Mobile hotspot for my iPad
- identifying and remembering songs to get using the Soundhound music recognition app.
- Listening in to the Police/Emergency scanners in my area using the "scanner radio" app
- keeping track of bills/budget with the pageonce app (one of my personal favorites)
- Remote desktop to my home pcs or work pcs (for an emergency situation and if I dont happen to have my ipad with me) with Splashtop remote desktop.
- Use google shopper to ensure I'm getting the best price on pretty much anything I buy thats $50 or more (this has saved me HUNDREDS of dollars over the course of having my phone, seriosuly)
- weather updates and alerts
- Navigaion with google maps
- Note taking on the go with springpad
And the one that that I dont do with my phone at the moment that I REALLY want to is to scan my car's OBD2 problem codes with the Torqu pro app and a bluetooth obd2 plug (saves you 100 bucks on a dedicated obd2 scanning device and workes just as well if not better... awesome.)
