Here's the bottom line....these DEs are amazing!:) I really like KDE but XFCE has so much to offer. It's just a matte of using it. I can tel ya, if I get a netbook, Linux is going on it and it'll have XFCE for sure. Fast and lightweight. Windows is no where near Linux! How can people continue to use Mac, for that matter? Linux has so much to offer! Wow!
the find file function in XFCE is jus great. I wish it were in KDE because I like using KDE. Not so mucvh tht it's my favorite, but only because I started with it and am most familiar with it. These other DEs, though, are becoming contagious. E17 is slick and cutting edge. LXDE is like an old trusty friend. XFCE really shines!:)
All in all, I like 'em. Iust have ot learn some of the ins and outs. for instance, KDE allows me to hit Ctrl Esc to get a menu of all running processes. then, I can shut down what I wish. This doesn't work in XFCE, AFAICS. So, I simply need to learn a new way. No big deal, just gotta learn some new moves.
