Is there something I'm missing?

I just got my new IPOD Touch, and downloaded the new Zagat Guide app. Perfect, except that it requires WiFi access to use it.

But, the whole point of this kind of Guide is to use it "on the fly" when you're standing on some streetcorner wondering where to eat. I don't have WiFi access on every corner. I thought the content would be downloaded to the IPOD, but apparently only the operating software is actually present, you need to go online to search for anything.

Is there something basic I'm missing? Do most apps require WiFi access??

The thread title should more appropriately read:
Zagat Guide - app needs Wi-Fi access

But to answer your question. No, many apps do not require Wi-Fi. It's a matter of how the software developer designed their app. Not your iPod touch's fault.

Lot of apps. do need an Internet connection.

For instance, a lot of Wifi finder apps.

Reason is, they store the data and the database on their web sites and the apps. just connect and retrieve that data to the Ipod Touch or iPhone.

That is how Google Maps works and that is why GPS Turn-by-turn apps. like TomTom charge $100 because you have to download the maps to the iPhone and store it locally.

Lot of location-aware apps. need Internet connections too, which make them useless if you don't have a mobile data connection or you don't want to pay for data roaming overseas.

Maybe since Google now owns their own maps instead of licensing the from Navteq or TeleAtlas, they will give you the option of downloading the maps instead of streaming them.

I think it's kinda a trade off. If you had all the data stored locally, you'd be guaranteed that some of it was out of date since you last updated your software. At least this way if you can connect, it's going to be current.

It's like the old phonebook problem. The day after it's printed, it's out of date.

Agreed, but it would make sense to give us the option. Since the IPOD Touch only has WiFi access, and not 3G, the user is limited to places where they can get WiFi access. That's a huge limitatation on a tool designed as an information source for travelers.
