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.
Well. that is open to debate, fragmentation has been the saving grace of Linux in the security sector all these years, and writing a patch is usually not the job of the original developer but the distro maintainers. Usually this patch only includes a few lines of code to optimize the app for their specific kernel and to point the install to the correct libs.
I can tell you right now that Debian, the main brains behind the GPL, and the Free and Open Source Foundation and anyone who have anything to do with GNU will not go along with this, and I will be surprised if the other big movers and shakers go along as well, it just feels to much like proprietary standards are being forced down on the community.
Maybe we over-react, don't know, but they will have to go a heck of a long way to proof that this is the future, and another thing, the moment they add the first paid for app on there it will be to their doom and demise, aka LinSpire?
The whole philosophy and ideals of Open Source runs much, much deeper than the need for a user base. something we must always remember!
