One of the most underrated Star Trek series, in our book, "Star Trek: Enterprise" or just "Enterprise" is now available for viewing online.   CBS Studios has made all four seasons watchable for free on CBS.com.  Star Trek: The Original Series is also available for viewing through the CBS website.

From our understanding, Apple iPad users should also be able to view the series.  If not now, then soon since it appears that CBS is in the process of testing and slowly releasing all of it's streaming content using HTML 5 instead of Adobe Flash.

Since CBS also has a partnership with TV.com for TOS streaming, we'll be curious to see how long it take Enterprise to migrate to the TV.com iPhone app.  I mean, how cool would it be to have TOS & Enterprise available for view at anytime?  We'll see if the new HTML 5 standard video will play nice with the upcoming iPhone 4.  We'll have one in our hot little hands Thursday and will keep you posted.
