Dont be silly guys. A big limitation of linux has always been the fragmentation and fiddlyness of installing things that work for that specifiec distro and version.
Bringing distros inline will mean developers can focus on the product rather than patches to make it work for this distro and that one.
Quality of apps will surely improve because developers will immediately cater for all distros with one release and wont have to tear their hair out because of a tiny little glitch with a specific distro. The user base for one app will immediately increase as every distro is now able to install and use it, this will provide linux with the power it needs the power to make it worth while for developers to develop for linux. And Open source isn't the alpha and omega, not alot of game developers will develop for linux plainly because its too fragmented and targeting for example only one distro is not worth the effort. If the user base is now the entire linux community regardless of distro things might change as it might just become worth their while. Linux needs to become more commercial they dont need more geeks they have enough of those already.
