I'm looking at getting a tablet soon myself. I would say don't tie yourself to an iPad just yet. As other PP's have said, there are other tablets out there, and this is the time for new offerings to come out, in time for the holidays. Google is apparently going to be announcing a new version of it's Nexus next week, and the Nexus gets absolutely rave reviews. Microsoft is debuting it's Surface tablet on Friday (I'm leaning towards this right now personally), and that's supposed to have some super features available.
I have a Kindle Fire right now, which I love, but the downfall for me is it's small memory. I'm not always near a wifi connection, so I'd like to have the ability to download a whole bunch of stuff and view it while I don't have a connection. With my Fire, I'm always afraid that I'm going to run out of space, so I don't download as much, and consequently run through all the things I have, with no chance of getting more since I'm not near wifi.
