life. Moblin is a Linux-based operating system and is only for
netbooks. Another netbook feature that makes them especially green
is their no-moving-parts-storage -- which means they should exceed
the lifespan of the standard notebook. So netbooks are one of the
greener options available. And no matter how well Windows 7 is
received, it can't beat the cost of Linux on a netbook."
