Essentially, it's a Mozilla based alternative to the Chroium/WebKit based ChromeOS.
It does have potential ... but I see it as better suited for tablet/slate computers, or public internet kiosks
rather than regular desktop/laptop systems running atop your main Windows, Mac OS X, or Linux OS.
Another potential use would be as a "splashtop" type OS ... an optional fast boot OS that runs directly
from a chip on your PC mainboard before you load your main operating system from the hard drive.

SeaMonkey = Swiss Army Knife: It's versatile, reliable, and contains useful tools.
