I currently own a first generation 3G iPad, and honestly have a hard time recommending it. The 3G iPad is the ONLY unit that has the GPS built into it, so if you are getting one to use with the Navionics apps, you'll need the 3G version and they are $800. You don't have to install a SIM card, so there are no charges to use the 3G network unless you purchase a SIM card, or transfer one from an existing service. Note that the iPad uses a smaller micro-SIM card that is not the same size as a typical cell phone (of course). You can either get a new SIM card, or if you want to share one with your existing phone, you can cut the card to the smaller size (cutters are available via Amazon for $6) -- they then come with an adapter so the card can be used in a regular phone again -- it does not impact functionality of the card (I've done it and have one of the cutters).
I find the iPad does lots of things, none of them particularly well.
- Transferring my home audio and video files to it is extremely painful (no USB or SD card slot)
- iTunes bloatwear sucks huge and is very unstable.
- The unit does not play all video and audio formats.
- The onscreen keyboard sucks, particularly if you have fat fingers so doing emails on it is next to impossible.
- Unit won't play Flash video
- OS is proprietary
- Cannot see the screen in sunlight or with polarized glasses on -- using it on the boat is very challenging
Things I like:
- Battery life is excellent
- Startup is instant
- OS is reliable and few bugs
- Navionics app is excellent
If I was to do this again -- and I just might -- I'd take a long look at the
Asus EeePad Transformer. GPS built in, keyboard docking station transforms it from a tablet to laptop. It runs Android 3.x which is an open source OS with tons and tons of excellent and free apps. It has a dual core CPU with 16 hours of battery life. Plays Flash video. Has USB and SD card slots.
It's HALF the price of the iPad at $399.
