Phone hunting

My phone contract expires next month and I'm considering coming out of a 'pay monthly' contract and just buying a phone and getting a 'sim only' deal. Over the course of a couple years there's not much difference in the cost but this way I would have the freedom to sell the phone at any time. I hate being tied into two-year contracts with the big networks.

Anyway, I've been looking at phones to buy and I'm really quite taken with this Samsung Galaxy Note 4. It's a monster of a phone with a huge screen, a fantastic camera and battery life which seems to be better than most of the latest phones.

I just need to negotiate approval from the financial controller now.
