A service like this has some nice overlaps with one of my favorite Palm OS programs,
Vindigo. I love syncing my most used cities to my device and being able to find the movie times near where I'm at, a restaurant nearby, directions to the museum and a nearby parking garage. I like that it stores the information on my Zodiac2's cavernous RAM so that I can be stuck in traffic and find a wbetter way to getto where I'm going.
I look forward to using Google "Local Search" on my next Wi-Fi enabled PDA, but for now Vindigo works marvelously in getting me where I want to go and helps me discover new restaurants or whatever.
