The most important change that ACDs require now is a change of specs and not whether to iplement an isight or not.
Its about time we see a change and i hope this change isnt a design change, but only a spec change!
I think the smallest apple would go is a 17" widescreen. It would be a pretty smart move considering they could jump on a lot of the money people usually spend on alternate LCDs for their minis.
I think it's about time for Apple to lower those prices on the ACD's. That 20" has been overpriced for quite some time, yes I understand that the design and casing is a little more extravagant than the comparable Dell. I hate to say it but for the price of one ACD you can get 2 Dells with the same specs. (20" that is)
