After using Archlinux for a year I am back on Ubuntu 12.10. Ubuntu 12.10 is an absolute bliss. It is a complete hassle free desktop environment. If Ubuntu had support of hardware and software developers, it is definitely ready for some serious competition.
On the other hand, I am not so happy with Linux kernel which is being updated every 3 months yet it performs terribly when it comes to power management. There is a new power regression bug every few months.
I have tried several WM from DWM, Awesome to XFCE4 and Gnome. There are things that Archlinux community doesn't want to do as a part of their philosophy. I am not saying it is wrong. I just like already set up distribution for now.
