I have a 64GB wifi iPad 1. It serves my purposes, but is starting to get a little sluggish. I had planned on waiting a while longer before upgrading, but with the introduction of the iPad 4 today, I just ordered a refurb 32GB iPad 3. It was $469. One of the factors driving the decision was the 30 pin dock connector. One of the main things I use my iPad for is watching movies while traveling. I have the composite video cable for this since most places I visit have at least composite hookups. Sure, some have HDMI, but almost all have composite.
This coupled with the fact that I don't need the latest and greatest lead me to click the buy button.
