A few requests:
I am a happy user of Linux *as a server*. I have tried to use it a few times as a desktop install and wiped it each and every time. Here is my wishlist for a Linux desktop (some of which may have already happened, knowing FOSS):
1) apt & yum and others are great. I have my server updating once a week without any problems. However, trying to figure out which packages/software are available, what they do, etc, etc, could be made simpler by (for example) having a, er.., product, which lists the available packages by names and/or categories and/or keywords (etc) with a description of what each package does.
2) Installation of packages should create an appropriate icon on the desktop or item in the appropriate menu list. Yes, yes, I know *some* packages do this already, but not all. And it should include an easy "uninstall" option for when you've realised you've installed the wrong package.
3) a pre-configured version of Wine or equivalent. Yes people, realise that the majority of users you want to attract (myself included) will have a stack of old MSWindows program they still want to use. Deal with it.
4) I perfectly agree with some of the comments - some packages are just too much pain to use. GIMP and OpenOffice come to mind. Did someone purposefully go out of their way to make them as un-windows as possible? Somebody *please* tell me how I can get OpenOffice to display my documents in something akin to MSWord's "Normal View"? Is it so hard to understand that some of us *don't* want WYSIWYG until we're ready to add final formating to the document? Heck, MSWord has (had?) a "Word-Perfect compatible" command which allowed ex-WP users to use WP command in MSWord.
Let's face it - Apple took a *nix flavour and customised it so that even the grand-folks could use it.
