If looking at an Android device, be double sure it has a GPS chip in it (assuming you still want an all-in-one thing). Not all do.
Then, you would certainly have a "PDA" with thousands of apps available, but be aware that you could only run Android GPS software. There is lots, some good, some not so good. Even iGo (based on an older Amigo), which can use all the latest maps the same as any other iGo product.
