i have been using an emac for the last 1.5 years and it is a great machine, i did all my video editing, web design and 3d animation projects on it, it never let me down. i am sure that these new models are great buys, but i am selling my emac right now, and i know that i will never buy one again. the only reason is that emac is the most noisy computer i have ever used. it is impossible to live in the same room with an emac, and when it is working, you can hear it from far far away. leaving it open during the night, which is crucial for the 3d renders i make, is impossible, because you can't sleep.
so, if you are thinking about buying one, please take the fan noise into account. i didn't know about it before i bought it, and i was simply shocked when i first used it in my room.
cheers,
taylan
