Just to throw in one more thing, there was a couple of rumours that said Apple might refresh the full size iPad to have the rumoured smaller dock connector. But that really isn't a big deal, so I would just buy it now.
Bought my first iPad a few days ago, never thought I needed one but its great! To be honest I definitely didn't need one, I wanted one ha! The plex app is AMAZING if you have a media server! Most refined app out there.
