I don't have problems with Viigo being a memory hog. killacam865, look in the Aftermarket Software section here. There are many discussions about Viigo there.
Heh... the 8330 has more memory, so maybe that's why it doesn't seem like a hog to me. But I don't leave it Viigo running all the time. When I want to read my feeds, I update them, otherwise it's not running.
