Thanks Aryk for the link to this Gizmodo Ultimate Tablet Showdown, comparing the specs of iPad vs. PlayBook vs. Galaxy Tab vs. Slate.
The latter point will go away (in theory) in time, but the former is fairly normal for Apple... the iPod's list of features is going to come in pretty much last compared to any other mp3 player, yet it dominates, even without expandable memory, an FM tuner, OGG playback, etc. I don't think the iPad will "lose" because of this though. On that note, Apple, you guys still haven't contacted me to send me a review unit.... time to get on that mmmkay? :)
