There are several GPS applications available for the I-Pad. I use one from Geocaching.com that's excellent. There are a lot of map and navigational apps available too, depending on your needs.
They work well over 3G and wireless in my experience.
It's a handy, easy to use little bit of technology IMO. You can even turn it into a phone with one of several SIP applications.
Believe it or not, you can't play quicktime videos on it. Hopefully Apple will address that soon.
Battery life is amazingly good IMO. If you're a Kindle user there's an app for it as well as an Ibooks reader.
Mrs. L does indeed carry hers in her handbag. They're very lightweight.
Where they lack is in real business applications. You can open and read any MS Office files, but to do any editing you need a DocsToGo program. It works, but isn't anywhere close to the MS products.
Overall though, I love the thing.
I hope you find this useful.
Thanks to you and All. This has been helpful. Of course I’ve tried to read about it online but there’s really too much information for me to process out there. I knew Freepers were the best place to go. Now I know I have to get the M3 version, which is more expensive, and need to find out what the monthly will cost me.
I have tons of Quicktime videos on mine. Mp4 and m4v I use Real Player to download from youtube and it has a converter built in, but I use a Turbo HD device for big files. You can also use Handbrake to rip DVD's into playable format. I don't like the way iPad handles Photos or Movies, so I have iTunes Playlists, like, iPhoneMovies, and iPhonePhotos, that I drag the videos and picts into. Makes it easier for me to find them on both the iPhone and iPad.
Buy Pages, Numbers, and Keynote for iPad and you can... opens and edits or creates MS word, Excel, and PowerPoint documents. Each app is $9.99
