I understand that you feel Apple is 'nickel and diming' its customers with adaptors, but from my experience working at an Apple reseller, the vast majority of users leave these adaptors in the box after they have opened it (most people never connect their laptops to an external monitor, we have to remember that the MacRumors users are not 'most people'), and this is why I think Apple have decided to stop including them.
If Apple were to include adaptors, which ones should they include - all of them? just in case you need VGA and I need DVI and someone else needs Dual-link DVI.
I'm not defending their policy, and maybe a compromise would be to offer a voucher with each Mac for one free adaptor or a discount off the dual-link DVI, then people get the cable they need (if they need one at all) and Apple aren't wasting money and resources on components that stay in the box most of the time.
After all, Apple seem to be committed to reducing waste with their products.
That said, my G4 PowerBook came with DVI>VGA and S-Video>RCA and both have been very useful over the years.
