you people just don't get it.
Full screen apps were made with small laptops screen in mind, not for 27 screens or multimonitor configurations, apple have said several times that their most sold computers are macbooks, so they have create some new functionalities for these kind of costumers.
I, for example i have a 27 imac that i use for a living, i'm never gonna use this full screen mode(why will i waste all the screen real state?) and neither launchpad, spotlight is way faster to launch apps for me, but that doesn't mean i have to whine just because this are not meant to me.
If you don't like the new app then don't use it, is an extra in the os, it doesn't affect the way you use your mac, just like frontrow didn't dumb down the so.
I can understand the complaints about spaces, apple screw some people workflows, i give you that but i dont get the complaints about launchpad, like i said, if you don't like it, don't use it. I don't like cmd+tab to switch between apps but i don't whine day and night about it's existence and how it does not suit my needs.
I don't know why people say mac users are like a cult and that they eat everything steve jobs made without hesitation, i've never seen this kind of whining about everything in other platform users, jeez.
