Because they can't provide worldwide coverage. To cover near-polar areas, inclined orbits are necessaries. Since the geostationary orbit must lay on the equatorial plane, it doesn't suit to fit GPS requirements.
It depends on which satellite you are talking about. However YES, it is closer than any geostationary weather satellite and it is closer than any GPS satellites.
There are 24 satellites in the United States GPS system that are active. There are 6 more that are "asleep" and saving power until they are activated to replace one of the 24 satellites that has to be taken off line for maintenance, damage, and so forth.The Russians also have roughly that number of satellites in their GLONASS system.Europe is deploying satellites in its Galileo positioning system.Japan has or will launch its first satellite in its QTZZ positiong system.There are also about 4 satellites in WAAS, the Wide Area Augmentation System that makes GPS more accurate. Europe's version of this is EGNOS, or European Geostationary Overlay Service. It has 4 or 5 satellites.
A GPS stands for Global Positioning Satellite and is a device which uses satellite location to determine your position. A caddie is a device which is a container or carrier for another item. As such, a GPS caddie is an item which holds a GPS.

GPS satellites are not in Geostationary Orbit (GSO); instead, they operate in Medium Earth Orbit (MEO) at an altitude of approximately 20,200 kilometers (about 12,550 miles). This allows them to provide global coverage as they move relative to the Earth's surface. In contrast, GSO satellites maintain a fixed position relative to the Earth, orbiting at approximately 35,786 kilometers (about 22,236 miles) above the equator.

Because most satellites are not 'geostationary'. A geostationary satellite orbits the Earth at the same speed that the Earth spins on its axis - such as the GPS grid, or TV relay satellites. Most satellites travel faster or slower than the Earth spins.
Geostationary is the moving orbit in the plane of the equator. Geostationary satellites are 22,300 miles above the Earths surface, and remain stationary at a fixed point. Weather and communication satellites are examples of geostationary satellites.
Geostationary satellites are the ones used for GPS satellites.

Yes, GPS and GeoStationary satellites are two different things.

satellite signals
GPS is an abbreviation of Global Positioning System, a receiving system that utilises regulated signals sent from geostationary satellites to triangulate its location upon the Earth.
Low Earth Orbit (LEO): Earth observation, remote sensing, satellite communication. Medium Earth Orbit (MEO): Global positioning system (GPS). Geostationary Orbit (GEO): Weather monitoring, telecommunications, television broadcasting.
