Did we honestly need another thread, there are plenty already.
however as we do...
Go to a store, hold both the Note (because essentially note 2 is going to be same size or thereabouts) and the iPhone 5 in your hand and see which feels more comfortable to you.
I wish stores let you make a call with the device, seems like the most basic thing they could offer. You wouldn't go buy a TV without being allowed to see the picture.
The feeling of a bigger device being held up to your face and the getting the ear piece aligned up so you can hear everything can be finicky as the device gets bigger. May not be a problem if your using a head piece or Bluetooth, but if using a phone traditionally could also be a deal breaker.
As for android v IOS, well I personally think the pros and cons of both have them at an even play field at this current junction.
Jellybean addresses a number of Androids issues over the years, and iOS whilst as rock stable as ever, and on the iPhone 5 it is super quick, feels a little dated but in the same way that a Rolls Royce is reliable and classy, but that flashy Porsche around the corner still is tempting me...
I've personally gone for the One X, the biggest android device I've owned, and one that at times still feel a bit too big, especially when I hold it to my face/ear. I tried the Note but was just out of picture due to the size. Also have the iPhone 5.
For taking photos, texting and more importantly for me making calls I prefer the iPhone 5. Call quality is excellent, and just feels better as a phone. The camera is very good too.
For all the other stuff, messing about and tinkering with the device. Browsing the net etc., the one X beats it.
So I'm sticking with both devices for now...
