Okay, so you might be happy with your Windows 7 installation on your spiffy new Asus Eee, but somehow you miss the Linux installation on your old netbook. You don’t have the patience to install a dual boot, but you really, really want to have Ubuntu running alongside your Windows insallation, you might want to check out Portable Ubuntu.
What does Portable Ubuntu do, exactly? Portable Ubuntu for Windows runs an entire Linux operating system as a Windows application. As if that weren’t cool enough, it’s portable, so you can carry it on your thumb drive.
