Over at TabletBlog, thoughtfix ended his item comparing the Nokia N810 and N800 Internet Tablets with this note:

"I realized that there's more to a GPS than simple navigation. The Nokia N810 is a 'location aware' device and is open to location-based applications.... People can meet from across a rock festival without getting lost."

I think that would be a really great application for someone to write -- "I'm here, where are you?" And icons representing you and me both show up on a Google map.

Sure, when we're talking about two people cellphones might be easier to use. But what about when it's 20 people? (A scout troop at the World's Fair. A family reunion at DisneyWorld.) Or when, as Daniel suggests, -- the people don't know each other yet?

Definitely looking for this.
