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 ?

That's nice. Now how many others of similar quality? I can name at least 10 for both the PSP and the DS.
