Actually, no. Having multiple targets requires more shots. Ammo cost. Every company has to figure out how they will handle the mobile market. They have to pour resources into android and iPhone or else into a bridge tool like appcellerator. Bridge tools have costs because the require customization time.

Compare this to modern Web Development. There is only one family of targeted platforms: html and Javascript. That's it. Don't like Javascript? Tough. But at least you don't have to learn and pay for multiple, vendor-centric tech. I actually long for a standard platform for native mobile development.
