It was exactly one year ago today that I published my original "The 10 Best Linux Distributions" and it's time to put forth a new list for this year's best. Without looking at the old list, I've decided to compile this one from scratch. This 2009 list takes several factors into account for placement in the list: Community support, commercial support, software variety, update engine and distribution frequency. Even for old Linux salts, there are a few surprises on this list. For starters, Ubuntu is not number one.
