Help me decide on what type of phone I should get?

[aizawasuki]

I'm 18 and soon I will enter college.
I've had my Sony Walkman w80i for almost 5 years and it's about time I get a new phone. At first I was considering a Nokia Lumia 800 or something but after doing some research of it, I start to have second thoughts about it. Anyway here are a few things;

- I don't want anything over-priced eg Samsung Galaxy phones or iPhones, but REASONABLY PRICED (don't get me wrong, i'm not shouting, just highlighting for your convenience of reading).
- I'm pretty rough with my phone, so I'd like something DURABLE. (The plastic corners of of my old phone are cracked because I kept flipping it in my hand)
- Something not so humongous like those 'phablet' phones, although I do have huge hands. Just AVERAGE-SIZED
- I'm not a social-network freak, but I would like to QUICK ACCESS TO TURN ON MY WI-FI.
- A fair RAM at least 512MB. ( I'm impatient with lagging phones)
- Great camera quality, especially for RECORDING VIDEOS.
- LONG BATTERY LIFE. Not extremely, but anything close enough. I use 2G.
- MULTI-TOUCH, if possible.
- I like to talk to people with LESS INTERFERENCE, so I don't want so much metal attached to the phone.
- GREAT SCREEN RESOLUTION. (I've had enough of pixels)

Your suggestions don't necessarily have to match all of the criteria above exactly, I just really need your help! My entire household's making fun of me for not catching up with the smartphone mania! Your help is greatly appreciated. Please??
