Is this the beginning of the end for Radio Shack?

I used to go to Radio Shack all the time – in the pre-computer days. I spent a lot of money there. But they appear to be history. I haven’t set foot in one for 4 years – they have nothing I need.

Today they announced the closing of 500 of their stores – roughly 1/9 of what remained after the last cycle of closings.

Will they be able to survive? In a big box market, is Radio Shack irrelevant? Is this the end?
