It's already being adopted as a new display connection standard.
Adapters will only be necessary for a finite amount of time till monitors come with it as standard.
It's the same as removing SCSI and ADB ports in favour of firewire and USB. People complained about that at the time but look at it now.
Hey hey hey, I like my usb and firewire as much as the next guy, but what they hell were they thinking? No SCSI? OMG! Now how am i suppose to use this 25 year old printer and 24mb hard drive without a scsi port!!!!
