The N270 is good enough for Windows. After things are loaded into RAM from the Slow SSD the processor does a good job. I remember running Windows on a 350 MHz Pentium 2. I had to upgrade to a 450MHz Pentum 3 to run DivX movies. The N270 is equivalent to 800 MHz. Linux needs a 500 MHz processor (Light Distribution - XFCE) or a 1 GHz for a KDE environment. Windows is more feature rich than KDE. Supporting more devices and background services such as Anti Virus.
