I debated going the mywi route, but I don't like not having the latest firmwares and having to rely on my iPhone battery for my connection. I'm willing to spend a few extra hundred dollars for ease of use.
Update: Canadians are getting the iBookstore

Very pleased with this. Sure it might be a little overpriced and lacking a few features, but it's great having both the amazon kindle app and the iBooks app available. Plus the free previews are fantastic (I think some of KTrain's were upwards of 40 pages).
