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 ?

These don't look that much different, granted Asphalt 5 looks a little better but I think NFS Shift aims to be more realistic or something.

But really I know how those games are controlled. It's fun for 10-15 minutes perhaps but I want more.
Now this is a racing game that's both fast and requires precision:

Honestly I can't think of a better portable gaming system than the PSP. Sure some may consider its library to be inferior to that of the DS but if you add emulators for NES/SNES/Genesis/GBA/PS1 (which runs flawlessly) it simply can't be beat.

Not saying the iPhone or Android-based phones are bad at what they do, but when it comes to gaming it's simply no competition.
