Here's the story: I bought this netbook for my mom. Figuring that it would be a great little laptop for her to kick around the house with, easy to use, decent battery life, perfect for what she needs it for: internet, email, pictures. It worked OK for what she needed it for. There were a couple of problems.
1) Processor/General Performance: With the default ubuntu 8.04 installed, the performance was pathetic. Period.
2.) The SSD went bad. Yeah, I knowwhat are the odds of that right? The good part was that Dell sent me a new one. The bad partwas I had to talk to Dell for 45 minutes...

While she was waiting for her netbook to get fixed, i loaned her one of my other laptops. 1.4Ghz 15" screen, 1GB RAM. Needless to say, she wants to keep that one. So... here I am with a Dell mini 9....

The first thing I did after installing the new SSD was to replace the OS. I chose Moblin (see my other post regarding the wireless config). Moblin was nice, fairly snappy, quick to load, quick to shut down. But I didn't really like the UI all that much. It was confusing to me. Plus, without Facebook integration the idea that you can call it an OS designed for social networking is sort of laughable.

Next up: Ubuntu Netbook Remix UNR (9.04)
This one was good. In fact I'm typing this post from it! However, there was one glitch. Apparently if you switch from the default UNR desktop to the classic desktop it throws out some sort of error. What you are left with is a blank desktop. With no icons. Even after a restart the blank desktop returns. Here is how to fix it:

1.) Right click on the screen
2.) Create a new launcher
3.) for the name and the command type: xterm
4.) click OK
This will create a desktop icon which will give you access to the xterm terminal.
5.) Launch the icon and type desktop-switcher
6.) Select the UNR desktop. This will take you back to the standard launcher type setup.
From here. open a terminal and type the following:
gconftool-2 --set /desktop/gnome/session/required_components_list --type list --list-type=string ["windowmanager","panel"]
7.) Download this file: here
8.) Double click the file
9.) restart your computer
10.) ENJOY Ubuntu Netbook Remix!!

Besides that "minor" bug, its a great netbook OS.
