The Macbook air sounds great, but they're out of my price range.
Remember that iPad's are not stand alone devices. Meaning, you will want a heavy duty case (like the Lifeproof case), a bluetooth keyboard, and then apps to run on it, plus the additional warranty. Plus, if you want to use it for GPS, you will either need to buy a GPS puck to plug into it, or buy the cellular equipped models with the built in GPS chip. At the end of the day, the iPad is not that much cheaper than the MacBookAir...which has all the software you need already.
Keep in mind also that Apple has a refurbished product store for ipads, MBA's, etc...
