So, you just picked up your new 3G-enabled iPad from the Apple Store and are trying to figure out which apps can best take advantage of that device’s expanded connectivity. Wherever you go, these five iPad apps will shine on your 9.7-inch tablet computer.
1. 
Similar to the $7.99 Topo Maps iPhone app, the iPad version provides access to more than 70,000 topographical maps across North America. Maps can be downloaded individually for free with a wireless Internet or 3G connection.
3. Zinio Magazine Newsstand & Reader for iPad
While the iPad is a superior eReading device to the Kindle on so many levels, up until now a wireless Internet connection is required to download new things to read (the Kindle offers quick data connections when downloading new paid content). With a 3G iPad and the free Zinio Newsstand app, you can now tap into thousands of magazine titles wherever you travel.
Rolling Stone, BusinessWeek and the Sporting News are among the iconic magazines that market individual magazines and longer-term subscriptions via Zinio. The app also has a number of niche and special-interest publications.
4. Twitterrific for iPad
Until the official Twitter app for the iPhone and iPad becomes available, this free application is the best way to tweet on the tablet. Like the scores of Twitter apps already available on the iPad, Twitterrific is only effective with a network connection. Those 140 characters need to be transmitted through something.
5. Zagat to Go
For more than a decade, this pioneering restaurant guide has reinvented itself on multiple mobile platforms. From primitive Palm devices, to the iPhone and Android platforms and now on the iPhone, Zagat’s is an easy an elegant way to find good food near you.
While this $9.99 application offers foodie and travel guides in 45 markets across North America, new listings are updated each weekday. You never want to be in your own neighborhood or halfway across the world and not have access to the latest restaurant information on the fly. Another added bonus is that only one purchase is required for the iPhone and iPad.
