Practical question: Why get a 3DS or Vita instead of a tablet?

If you are creating games, know C#, and mono based platform like the one used for Android; you should check out the PS Suite Dev Beta. Maybe it would be a good platform, $99 a year for selling apps on it, not sure what profit cuts are or anything.

If you end up buying some tablet, if doing so in a store, make sure to talk to someone who knows the ins and outs of what does what and what you need.
