So, not even considering KDE? I'd love to know your reasoning. I'm genuinely curious, since I have been using KDE at work for some time (on and off). I'd like to know what a Gnome user thinks about KDE.
In the past, I've always installed Gnome on the computers that are too old or slow for KDE, or otherwise, the computers that I have to KNOW is not going to crash.
But, ever since KDE 4.7, even my 7 year old PC that I'm using as a server/media-center is running it perfectly happily without needing a single reboot. With all the eye candies and everything working perfectly. And for the REALLY old 10/12 year old laptops, that are still refusing to die, I put Xfce on, because it has become feature rich enough to keep me perfectly happy, while running incredibly smoothly.
But the thing is that both KDE and Xfce know who they are, and what they are trying to accomplish. And if you fall outside of their target markets: So what? Use what makes you happy. But, Gnome has this mentality of trying to please everyone at once. Which, admittedly, they sort-of managed to do in the past. But, the technology world is rapidly becomes so huge, and diversified that I don't think it's an option anymore. Now, more than ever, you have to know who you are, who your target market is, and what you can bring to the table that no one else can.
For Gnome's sake, I seriously hope that they can cultivate some good leadership that will (re)define the role they have to play in the grand scheme of linuxy things.
