I just sold my 13" Air on Craigslist for $200 less than I paid last July. Here's been my experience living without and I wanted to hear what others might have experienced. I purchased the new iPad with LTE in March and found myself using my Air less and less. There were several weeks where I didn't even take it out of my bag. My use case for the Air was email, web surfing, working on PPT presentations, and editing documents in Word when I was on the road, which was every other week. My employer now allows employees to access work email on iPads and iPhones, so I no longer need the Air to access work email. My iPad now gets all of my email via LTE or 3G, which my Air couldn't do and this saves me from having to find ethernet or a wifi spot when I need to type emails longer than I'm comfortable doing with the iPhone. As for document editing, I can also use Citrix on the iPad, which allows me to edit documents in Word and use track changes in a virtual environment. It works great. I use the iPad keyboard/dock that came out with the iPad 1. The real test will come on my next business trip, as I haven't tried a longer trip yet without a full fledged computer. I'm guessing the learning curve will be steep if I get into serious use situations. I'm also not sure how I will give slide presentations without a notebook video hookup. We have an iMac at home, which is our primary computing device. I figured that with all the functionality I'm getting with the new iPad, combined with already having an iMac and the possibility that the new Macbook Pros might be a huge upgrade, now was a good time to sell while I could get a good price and try the iPad as a productivity tool experiment.
