It wouldn't have occurred to me to go into one of these stores to buy an actual book, but I will say I appreciated having a no-advanced-planning-needed way to get a $4 HDMI cable or rechargeable batteries, or whatever other things regular electronics stores usually mark way up because customers have no other choice. Maybe now that so much of this is available same-day for free from online-Amazon, that's less compelling?
RadioShack is one of my favorite examples of a company that just couldn't evolve. They could have been a leader in the online electronics doodads market. They already had distribution warehouses to stock the local stores. One could have been converted to a pick&pull warehouse easily (in my non-experienced logistics point of view). They couldn't even do cell phones well.
