Hey. I recently bought a mini 2 last week and saw on it a dead pixel so i will be returning but i wonder is it worth to upgrade to mini 4? The things that i don't like my mini 2 are color gamut problem and 1GB ram (for future) other than that it works fine for me. I want to get a pro when i got some cash and until then i will use my mini. So what's your opinions? Note: If i want to upgrade to mini 4, i have to pay 50% more in my country. Mini 2 is approximately $280 while mini 4 is approximately $430. Thank you.
