I've had one for a couple of weeks now, awesome thing, only downside is no multitasking but that will come with the next OS update hopefully.
I've got a wifi one as it was the only one out at the time but apart from taking it to a mates to show him it hasn't left my house so the 3g requirement isn't there for me.
Mifi does seem like a good product/solution if you are only needing data on the move sporadically then it should be ok, it can also be used as a hot spot for any other wifi enabled kit you might have too. The only downside I can see is that its something else to carry around and it will need charging too. It's a shame the iPhone doesn't tether to the iPad as standard (it can if jailbroken) but I can see why it doesn't.
