im a new user to xfce, i have used it for 1.5 month and im absolutely amazed of the productivity of this desktop environment! Let me tell you, i am using XFCE on a virtual machine with 512 ram and one 2.4 ghz core i5 processor with Debian Lenny distribution. It is incredible how can it run with so little ram so smoothly and good. No matter what im doing or using it is stable and i the problems are minor. So i love XFCE and very soon i will migrate my main desktop computer which runs on Ubuntu 10.10 to Debian XFCE 4.8.
Big thanks to everyone involved in this great project !
