Go the 24".. you will NOT be disappointed!
GGet the 20" the brightness is not as good on the 24" I bought this one.......
I knew all those things about the iMac 24", but in $CAD, just an iMac 24" baseline, with nothing added is 2300$ plus, you have to add about 300$ for the tax. So it's like 2600$ at the end, and I have nothing but a 24" display ! That's why I went for the 20". I have all of the things I wanted inside, and I don't have to upgrade nor the RAM, nor the VideoCards...
I agree that an iMac upgrade may be coming soon, but I just couldn't wait any longer. Anyways, I think I'll have a good machine. Plus, I'll get Leopard when it comes out, so that's not so bad...
The only thing that I hate about the Online AppleStore, is that I have to wait about two weeks before they get it shipped to my house...I should have bought it to the AppleStore Laval, near where I live !
wow... you are a mirror image of me, except im poorer... I'm still saving for my Imac but im almost there, now its a matter of convincing my parents, or waiting for 10.5 or leopard. Damn all the Mac upgrades!!!
Brightness is NOT necessarily the selling point for displays.
I think the 20" iMac actually has a better quality LCD panel in it (check that out with Google or on the photography forums). I don't think anyone uses full brightness on a screen anyway, do they?
Also, you can't have "too many" pixels for displaying SD video. If you mean you'd be scaling it too large for full-screen viewing on a 24", then you simply don't make it full-screen - you could make your viewing window the size of a 20" monitor if you wanted (or bigger, or smaller).
Edit: read the posts on here (not sure which forum) (or probably on Google somewhere) on differences between S-IPS and S-PVA LCD displays.

Why would anyone opt to get a display with less brightness? That's just ridiculous.
the 24" is not as bright as the 20" fact
