I might be the geek of the band...
I have a MSI U100+ (with two batteries) upgraded to 2 GB RAM, but I don't use it at all as just 2 days later I had a good deal with a MSI U115 (upgraded to 2 GB RAM and the 8 GB SSD was upgraded to 32 GB) + the standard 160 GB HDD ! Windows 7 Home Premium + Ubuntu Lucid 10.04.
I added a resistive touch panel, but didn't like the single touch panel, so I just sent it back to the vendor. I was awaiting for a multitouch capacitive touchscreen, but as I now have a Samsung Galaxy Tab, don't know if I will buy such a touch panel now... ^^

May yes, may be not, as my first plan was to completly modify it and flip the display over the keyboard with a touch panel so it could be use as a tablet and/or a netbook with touch capabilty...
Otherwise, I also have an Asus N10Jb that I only use as a Media Center with an ExpressCard Tuner TV with Windows 7 Home premium and connected to a large monitor. Upgraded to 2 GB with a 7200RPM HDD for video TV recording.
This was one of the rare Netbook with an ExpressCard slot and hybrid GPU (Intel and NVidia) and HDMI out, all in the same machine. Really silent for a Media Center !
My best buy I guess, even if the battery life isn't as good as with the other Netbooks, but not a problem as I never user use it on mobility...
I have many other machines, but not Netbooks, so no need to mention them, except the Acer Aspire 1825PTZ with multitouch capacitive touchscreen, which also explains why I'm not in a hurry to modify the MSI U115, now... ^^
Sorry no pictures at the moment.
