I think in this case the cons outweigh the pros. I deleted my last account fpr reasons that have all been mentioned in this thread and am not going to get another one.
One of the reasons I thought it might be a good idea was that it's something more 'portable' - I could have it on my phone, have access to some support while I'm out & about/away from the pc. I just found the forum app though so it no longer matters. I'm a bit of a tech nerd too and like playing with my phone!
