I actually downloaded GB4iOS from emu4ios.net a few weeks back and have been playing Sapphire. It's a lot of fun when I want to take a short break from work.

So here's a cool question/poll:

What Gameboy hardware did you own?

I had an original Gameboy, a Gameboy camera (no printer), a silver Gameboy pocket, a Gameboy Color, and a red Gameboy Advance SP. The Advance SP was awesome but my roommate in college stole and sold it to buy cigarettes.

I also had a Virtual Boy and an original Nintendo DS.

*Edit: I also had one of those lighted magnifier/speaker rigs for the original Gameboy which meant I could play Metroid after dark and feel like a SPY!

I will never understand why the original software owners aren't monetizing Smartphones like mad.

These games could be ported to iOS and Android with minimal changes and still be succesful.

I tried a Final Fantasy for Android and it was decently playable, I was hoping for Final Fantasy Tactics (which according to Wikipedia was released in 2013 but only for Japan), and very especially for a followup. Square Enix seems to be among the very few that do that, I guess Nintendo doesn' want to cannibalize their mobile platform (they're facing a typical Innovator's Dilemma).

Absolutely. I would easily drop $10 on a proper emulator app and then even the same for a couple of games. Mario, Final Fantasy, Metroid. And my wife isn't really a gamer at all but she loves Animal Crossing. So I hooked her iPad up with an emulator and an Animal Crossing rom because she's just not going to carry around a dedicated gaming device.
