If you're in the market for a new storage/index.html">data-storage/index.html">GPS, you're probablty thinking about a lot of things: Does it talk?
Will it fit on the dashboard or a hiking pack?
What kind of maps does it have?

You're probably not giving much thought to GPS memory, especially expandable memory. But consider the advances in GPS data storage over the past few years and what you can do with extra memory -- like upload a complete street-by-street map of North America, for example.

Then consider the future and the detail you'll be able to include in your GPS -- Google Earth maybe?
If you don't have expandable GPS memory, you're going to be faced with buying a new model every few years. If you want to save some bucks as technology improves in this area, you may want to invest in expandable GPS memory now.
