Would you upgrade to a iphone 6 from a iphone 5?

I'm going to buy one but not sure if it's worth it.

I've had a look around, surprisingly eBay is actually more expensive than the apple store for any model:/
I went to eBay to find a bargain to only find the 16gb models are like 50 or so more than the apple store?

Only worth it if you upgrade to samsung note 4.It had more ram, better pic, better screen, and better audio. The iPhone still using 750p for resolution. 1080p should be the norm in 2014. The iphone is 3 years behind you're wasting money

I have recently upgraded to a iPhone 6 plus and my father has upgraded to a iPhone 6 and I think it is worth it, it's bigger, there's a better camera, it's faster, and it's got a better hd retina display.

I would say yes. Bigger screen, better A chip and camera.

The difference isn't astronomical. Stick with the 5 until Apple start neglecting it and practically render it worthless. Get a tablet if you want something bigger lol.
