Of course, I have a real Broadcast-spec monitor for video editing but I don't even try to get the monitor to match it (I set my monitor for printing/Internet.) But even that doesn't get used much. If the footage was well-shot, there isn't much need to fix it in post. I work with one cameraman who would probably throw a fit if I messed with his color anyway.
Apple set the monitor at the factory so that pictures from a digital camera will look good--that use is the most demanding requirement of the iMac market. I don't know if they have an Apple store in Finland, but the one near here had the iMacs lined up with rotating full-screen photos selected by the VERY fussy Apple graphics department.
BTW, did you see that Apple announced the new iMacs TODAY. You may be in a position to bargain for an upgrade / price drop--just tell them you want to return the one you just got and see how they respond.
When I got mine, Apple had just released Leopard and like the trendy I am, I immediately upgraded. THAT was a mistake. I had software I could not get running right for three months. But some application programs had updates, Leopard itself has had two, and importantly, there was a recent firmware update so everything is now running full speed. I upgraded the memory to full capacity (4 gigs) before I ever plugged it in the first time.
My iMac is, by FAR the best computer I have ever had the pleasure to run. It is beautiful, quiet, and blazingly fast doing difficult things. I hope it lasts a LONG time. "Remember the I35W bridge--who needs terrorists when there are Republicans"
For video editing I use an ancient Sony pro monitor which I also take sometimes to the studio - I know the feel of the picture. It's like having a favourite vocal mike that you are used to (U87 - though there's an AKG I like with my own voice. I do a lot of voiceovers and I have persuaded some clients to let me record at home. This makes me feel better about not driving into town. You can't be me, I'm taken
