Homedepot is where I got my last soldering iron. While I agree with the conclusion that

Radio Shack didn't just miss the boat, they sank their own ship when they switched from being the only place where strange electronic parts were sold, to being another cell phone shop.

I disagree with what that boat would be, they should have been more best buy\fry's than following hobbyist electronics in to the super niche that it is today. What I don't get is why they started to sell computers\ electronics then pivoted to brookstone crap gizmos and cell phones.
