I've tried to be patient with Ubuntu and there are things I really like about it such as it's ability to pick up hardware like an Intel Centrino, and it's package management. However, I still find the network switching to be flaky at best. I use my Thinkpad T40 at Home and at Work, as well as other places. I mostly use the wireless but I also use the gigabit Ethernet adapter in some instances at work and home. At home, I have no DHCP server. At work, I have DHCP for the Wired and Wireless network (these are two separate networks). Ubuntu has been a nightmare to switch between the various profiles. It's almost as if the network-admin app doesn't properly save the settings. It would also be nice to set the network profile at boot time much how Fedora and SuSE allow you to do it. So far, I haven't been able to find any kernel parameters that would do the trick.
I'm still not giving up yet on Ubuntu but so far, I'm not seeing any compelling reason to switch distros.
