I'm about ready to upgrade my LaCrosse 3-1 for an Acurite. Which is better option between the "Pc-connect" and the "Hub" option? From what I read the Pc-connect has to have a pc live 24/7 for downloading and the Hub doesn't, is that correct? Is that the only difference in these? I guess the data is the same only the way it gets to sites like W.U. Isn't the "Hub" method more secure as far as protecting my own data since I would need to leave pc on 24/7 with the Pc-connect option. Any suggestions are welcome. I'm planning on two screens in my house which I guess is not a problem. One more question, How much will being 24/7 slow my pc with the Pc-connect?
