It's the same for any complex program, smartphone or desktop. I have Picsel Smart Office on my phone and it has a boot time, because it's an office app and has to load resources to use the app.

And on his proposed solution, he asks developers to empower users, to not make users feel belittled, and at the same time he asks developers to trick users into thinking the full app has loaded. How can you avoid belittling someone and trick them at the same time?
