Thanks for the great Review. I am missing the most important point of Spb Insight (to me!)
Normal RSS Readers only get the informations from the feed (e.g.
http://www.heise.de/newsticker/heise-atom.xml)
You often get only headlines from the Feed - now comes SPB Insight - it can also download the Articles which are pointed to in that RSS Feed and so you can Read the Article instead of looking it up at the Website.
So you can Read all Offline after you downloaded that Channel instead of making an online COnnectiong for Reading the Articles.
With the Templates you also can go further and Create a newsfeed from a Page that DOESNT have Any Rss feed!
