Well no, the UI on a phone is severely dumbed down because it has to work with a smaller screen and touch input. You can do the same stuff, sometimes, but with more effort.
Like, I could program on my phone, if I wanted. But that would suck major ass. It has the same capabilities, but certainly nowhere near the convenience. Even just running two things at once. It's... possible... on an iPhone. But it's not a desktop with split screen. And, if it can do split screen, I really have to squint, right?
