1) Performance: We wanted to have a very high performance Pocket PC that can be used for personal information management. While at the same time, running a high speed CPU next to a sensitive satellite receiver degrades GPS performance significantly.

2) Upgradeability: The current generation of GPS receivers will certainly not be the last. More advanced satellites will be deployed very soon, and who wants to throw away an entire navigation device when the next generation receiver is ready? Mobile Crossing is committed to the long-term satisfaction of our customers, and we will offer upgrade kits at low prices to our customers.
