DP is to display what USB is to serial ports. The biggest advantage I see for the end user is that you can daisy-chain devices. Native Display Port monitors have come down in price lately, but a quick look around a few retailers will show that they are still quite expensive compared to HDMI and DVI monitors.

This is a bit oversimplified, but fairly accurate:

VGA - Virtually obsolete when it comes to new hardware.
DVI - Headed toward obsolescence, but still common.
HDMI - The current "in" thing.
DP - If it catches on, nice to have. If it doesn't, it's like HD DVD was before Blu Ray captured the market.

The biggest advantage to a DP adapter for someone without a DP monitor is that through the use of an Active adapter you can bypass the two-device limit inherent in DVI. AMD's Eyefinity has allowed me to run three monitors off of one HD6870 video card. Their six-monitor setup is possible by running two cards with Eyefinity.

What smarteyeball mentioned about a Passive adapter is true, assuming the monitor is DP. Like I mentioned, check the prices and a $30 adapter looks like a bargain.

I have one monitor running off the HDMI on my card, one running straight off a DVI port, and the third running off a DP connection on the card through an Active adapter to a DVI monitor:

(Card connection => Monitor connection)
HDMI => HDMI
DVI => DVI
DP => Active adapter => DVI

Your setup is great for two monitors right out of the box. Throw in almost any modern video card and you'll have two more if you want them. Add an Eyefinity card instead and you can add three more. Of course, at that point any money you save on not buying a DP monitor will probably go toward a new desk to hold all the DVI/HDMI ones.
