Good points, Nate. If you want me, I'll edit for the answer to say this, but I'll leave the decision to you.

comment About a weak topology on TVS
You are welcome. And yes, unless there some special property (like when you have a metric space) in a topological space you test continuity on nets.

comment Linear isometry between $c_0$ and $c$
In principle, I don't think that your idea will work, as you don't know what an isomorphism might do to your sequences. What you might want to look at is the convexity of the unit ball ( more concretely, the existence or not of extreme points).

Good point! I was too lazy to think about that. I'll edit accordingly.
