I couldn't disagree more that the setup needs to be made easier. Ubuntu
is just as easy, if not easier, than the Windows installer, and other distros I've installed in recent memory ask additional questions because it's nice to.
I have installed Ubuntu 10.x numerous times, so I know the installer quite well. It's simple... choose which drive or partition to install to, type in your username and password, then the time-zone, and that's it. Best of all, aside from the partitioner, it asks you the other questions it needs to
while it installs. That means you can fill in your info, then come back ten minutes later and the install will be good to roll.
openSUSE is a good example of a distro that asks too many questions though (I am not sure if 11.4 changed anything or not), but it could be argued that it's a good thing. After all, Windows doesn't give you the option of what to install and what not to install. openSUSE does, so it lets you fine-tune your install as much is needed.
I'd recommend giving the latest Ubuntu an install to a spare drive, then come back and say if it's too complicated to install or not.
If by setup you meant setup after the distro is installed, I am not quite sure what else a distro could do. While installing Ubuntu, it will ask you if you want to install media support, which means that right at the desktop, music, movies and even Flash will work. That also goes for the graphics, audio, mic, webcam, et cetera. Past that, installing apps couldn't be much easier, since it usually just requires loading up the app center where you can type in an app name and then download it without even opening up a Web browser.
If you need any proof of this, you need to drop by and I will show you the latest Ubuntu installer and setup process in person ;-)
This post took me longer to write than it takes for Ubuntu to install
This does give me an idea for an article though... comparing the different Linux installers!
