macbook enough for iphone app development ?

I decided to try selling few shitty apps after having seen what crap people acutally buy, tho it seems I need a macbook to make those

I don't want to buy an iphone on top of it so is the emulator thingy enough for development ?

I disagree with what he says, so I'll just criticize his typing because I'm being lazy at typing up a proper rebuttal.
