"To encourage computer makers to use DP instead of HDMI. This doesn't appear to be working too well."
Really? Seems like Apple has gone for DisplayPort with aplomb, and you can toss the new ATI cards into that ring too. Dell has also seems to be dunking a toe into the water with several monitors and machines sporting DisplayPort.
As for HDMI, its non-existant in the PC display market unless your monitor also is advertised as doubling as a telly.
I think we're going to be seeing a lot more DisplayPort. That said, I'm NOT in favour of Mini DisplayPort in use on regular size devices - there's more than enough space to stick a regular DisplayPort on these Apple machines - even the Adamo XPS has a full size DisplayPort. Too many variations of a standard for no reason causes as much confusion as having multiple standards. Apple's bad, really...
