I have a Droid Incredible. It has a real GPS as well as assisted GPS (cell tower triangulation). All GPS apps for the Droid work with both types.
iPhones still rely on ATT which has spotty voice coverage at best, but what you need is speedy data coverage as well. If you are outside of major metropolitan areas ATT data is almost non-existant, and voice connectivity is notoriously bad even in metro areas. ATT's network has been flooded with iPhone data traffic so even if you get a droid or a WinMo device on ATT, the service is still spotty as hell.
Most Droid apps are free, Google maps works flawlessly, I really have no need for anything else but Google Maps, as it does it all if you know how to use it. My bluetooth OBDII reader feeds realtime engine data to all of my (free) OBD Droid apps without a hitch. And can even upload the data in realtime to a website for later analysis. Verizon 3G data coverage is ubiquitous and fast even down here in backwater Alabama.
I'm not locked down into installing "Apple approved" applications from their "App Store", and when the Droid Incredible gets rooted, then I'll be able to run my choice of operating systems, overclock my CPU for greater performance and tether my data connection to my laptop WIRELESLY for free.
Not only that, but it can to those things all at the same time, Its called "multitasking" a twenty year old concept that the iPhone just cant get thier head around. Oh, and I can also copy/paste data between my apps. Copying and pasting, the simplest of data tasks, is still non-existant on the iPhone.
Android is is pretty as the iPhone OS, and just as fast if not faster. Its more versatile and Open Source.
Triathelete, I'm glad you enjoy your device.
