Well I have Microsoft Neptune running on one of my computers now, and I like it, but I don't think it is very practical for everyday use. It actually worked with all the display and sound drivers out of the box, and it seems somewhat stable. However, I realized that you cannot runany programs off of USB flash devices, it will say that they are invalid Win32 programs. If this OS continues to work, I have no reason to get rid of it. It even let me install my USB wireless N card that is suppose to require Win2k SP4 minimum to run, but it works! Thanks to kishy for the info.
