I like it
I just installed it this week and am pretty happy with it.
It's my first foray into Linux and having never touched it before but heard lots of offputting stuff, I was pretty surprised at how easily it went in.
The only difficulty was getting the right nVidia drivers.
It was a bit of a pain, but I'm semi-geeky, and familiar enough with command line from windows that I got it set up pretty easily. There's of good documentation out there.
I've downloaded and installed Asterisk (inspired by FT, of course), which I think is going to be a little harder.
Not sure why, but I opted to go this route, rather than to install TrixBox (asterisk+linux in one easy download), but I figured that I'd like to keep playing with Linux and I'd rather have the most user friendly flavor installed instead of what comes with TrixBox....
Of course, now that it's installed, I have no idea how to launch it...
But hey... I've gotten this far with no problems, and I like most of what I'm seeing of Ubuntu so far.
(Please note that, I don't really know what I'm talking about!)
