There's a couple of reasons that I can think of. First, you can buy a second dock and battery so it can be charged while you're using the other one. Convenient for long trips. But you can also connect it to the DC adaptor if you have only one battery. You can switch between docks in seconds.
Second, the modularity of the receiver portion is an advantage from both a design/manufacturing perspective and also potentially from an end user standpoint. Pharos can just design a variety of modules for the modular receiver to plug into, so if they want to design a unit with heavier duty battery capacity, or even a free standing unit with a display ala Garmin and Magellan, or a marine unit, etc., they already have a large portion of the design completed.
Pharos already sells a CompactFlash adaptor for this GPS, so the end user can adapt it for different hardware configurations without having to buy the GPS receiver part over again.

Second..Not sure why Pharos decided to use a special battery instead of your off-the self rechargeble AA or AAA..Any one know the type of battery thats in there? I would hate to go hunting for a battery when its life is up.

It's a 720mAh Li-Polymer battery with a claimed 6 hour life, so I would guess the decision was guided by high capacity and small size as compared to using off-the-shelf batteries. Among modern portable electronic devices (PDAs, cell phones, cameras, etc.), this is becoming pretty much standard practice. You may or may not like it, but it seems to be the direction of the various portable electronics industries.

Third..Is it NMEA compatible? Can any NMEA compatible mapping app or software work with it? Lets say I want to use TomTom or mapopolis.

It is NMEA compatible... I already tested it with Destinator 3 and it works just fine. In fact, the GPS hardware is available without software if you prefer to use another software package.
