Not really...console controllers don't CHARGE your device while you use them. Check out the suggested price for a iPhone case that also charges your phone:

You'll see they start at $80! So by that measure, these iOS controllers are actually competitively priced, for the features provided. $80 for the battery charging function, $20 for the controller "function" = $100. I'm speaking generally of course. Profit, R&D costs etc built-in somewhere.
Build quality, features and whether or not people actually want a battery-charging function, totally up for discussion. If people don't want a battery, then you'll have to wait for new models without it, and hopefully those will cost similar to the Xbox/PS controllers. Maybe we'll see iOS controllers that take AA batteries, others may be rechargeable, etc.
But the constant price comparison to console controllers (not just you, I've seen hundreds of similar posts all over the Internet since these controllers were announced), apples to oranges, makes no sense.
