After reading this thread I decided to start testing the free alternative, Piconews. I never got any further because it does what I need it to do: Maintain subsciptions, update, and display feeds. What more is there? I will try the other alternatives also, but it's hard spending time on it when the free one is good enough..
The only thing I miss in Piconews is being able to use the address book when forwarding feed entries by e-mail. Kinda cumbersome having to enter every address manually. Are any of the other clients integrated with the BB address book?
