And the similar: server-side/back-end is easy! Sure, there's an ubersmooth learning curve with HTML/CSS/Javascript, but once you get to heavy client side SPAs and supporting every device and format under the sun and then someone say "it's not good enough, try and make it feel like a 100% native iOS app - and no, you can't just write an iOS app" ...and good luck hiring a good front-end guy (at least if you don't do the expensive way of "hire 5 instead and fire 4 of them after two months" route).
