Here is how I plan on using the GN2. I have a
Peeble watch coming (sometime in Oct I hope). I wear a BT headset much of the time when I am outside and have BT in my car.
Google Now works very good for me and S-Voice isnt that bad either. Voice dictation on JB is awesome (I have a N7)
Add the Pebble, BT Headset/Car, Voice Commands/Dictation ... there will be many times I wont actually directly use the GN2 per se.... but rather have it be the hub that my Peeble, Car/Headset uses to complete the task I need to do. When I do need to browse the web, take a note, read a book... Ill have the GN2 right there for me.
Dont get me wrong... I love the GS3 and my Nexus 7..... but I am hoping to combine the 2 into 1 with the GN2.
