There are a few quirks that have been encountered, but besides that the experience continues to be good. One of the issues is when manually adjusting the display's brightness using the keyboard command when running on battery and then letting the system idle when GNOME knocks down the brightness even further, when returning to use the system the display will end up getting lit back to its original brightness and not what was set via the keyboard controls.
While benchmarks will come out soon that compare Windows to Linux (and maybe OpenSolaris and BSD too, since they are all supported by the Phoronix Test Suite), Windows 7 continues to run quite well and have the upper-hand over Linux in some areas. However, stay tuned for more information on that matter.
If you are interested in purchasing the ASUS Eee PC 1201N netbook, I still view it as a great buy and it can be found at Amazon (it's now in-stock compared to last month) or at NewEgg.
