Why do people think the Surface is too expensive?

Just wondering. I get the train of thought of "well I could get a full PC for that price". But then why don't people think the iPad is too expensive? Or do they? I feel like people don't complain about the iPad's price.

I guess from my view, for $600 I'd get a Surface over an iPad any day of the week because I feel like I can do so much more with it. And if the reason why people disagree with this is due to a lack of big name apps then ok fine, I get it. But I'd feel confident saying that the apps will be here sooner than you think.

So yeah, what's up with people saying $600 for Surface+keyboard is overpriced but an iPad on its own is not?
