If he wants to sacrifice stability for being always up-to-date with the latest shitware that Ubuntu is, then OK, it's his choice, but I don't wanna later be like "I knew it was going to happen" when he is going to realize, that his shiny, epic and awesome Dumbuntu installed on his Netbook is slowing and limiting it the bloody fuck down, when it comes to ABSOLUTELY typical tasks.
And about the desktop environments... it practically does not matter, because the processes running in the background are anyway going to render normal use of the Netbook practically impossible without waiting damn long time to finish themselves off.
Your hatred for Ubuntu is cute especially since you circlejerk over Debian, since Ubuntu is basically Debian except it's just better for desktop usage.
Especially because Linus Torvalds himself likes the concept of Ubuntu and it's derivatives.
That said, exactly because they are so important, it does frustrate me when I hit things that I perceive to be steps backwards. The SuSE rant was about asking a non-technical user about a password that the non-technical user had absolutely no reason to even know, in a situation where it made no sense. That kind of senseless user hostility is something that we’ve generally come away from (and some kernel people tend to dismiss Ubuntu, but I really think that Ubuntu has generally had the right approach, and been very user-centric).
And Gnome has a history for being bloated, both in CPU and memory usage compared to most other DE's, and we all know that netbooks don't exactly have a lot of RAM, a beefy CPU or a large battery pack.
Also a DE that requires lots of CPU cycles are bound to be a battery hog and thus make it have a short battery time and run hot, another big no-no for a netbook.
Not to mention Ubuntu (and derivatives) have better battery management implemented from the get-go, partially due to the newer kernel compared to Debian, and also since the DE's are slightly customized by the team behind it.
Much of the hard work is done for you, and so the system runs better.
While with Debian you'd spend a war updating the kernel to a more efficient version, and setting up a proper battery management system.
There's a reason Ubuntu & company is in the Top 10, only beaten by Linux Mint (which is basically Ubuntu derived, but with more things to make it even easier to use out-of-the-box)
