I've sold my MacBook Air to one of my mate and I'm very keen for an iMac. 1. Do you guys think the next update will be release soon and have a new design? If it is I think is worth the wait. 2. Anyone had an issue with the screen and be able to replace a new one until it's perfect without any problems? I'm very concern about the screen. 3. If I'm going to get one, which one shpuld I get? I will be using Aperture and Handbreak mainly and I will upgrade it to 16GB of RAM by myself (Any suggestion?) I'm thinking about the base model to save some money. Is the base model enough for my needs? 4. Also, I heard there is another issues if the user swap a new HDD/SSD inside, the fan will go crazy? Thanks guys.
