PC World has a reasonably useful article on
How to Buy a GPS. I give the author much credit for noting at the outset that if you don't go anywhere, you should go cheap, but if you travel to many different places regularly (salesperson) go big.
Which brings me to the quote - it relates to the timeliness of map updates for different units.
If you expect to use your GPS device primarily to find convenient java shops during occasional travels--or retail outlets that you've never visited before--working with less-than-up-to-the-minute mapping data is probably okay. And you can always turn to MapQuest for more-recent information.
No disrespect to MapQuest; I just find it amusing that the author assumes MapQuest (or likely any online site) will necessarily have more up-to-date information.
