Pretty obvious Best Buy and similar stores are having a rough time. Reality is that shoppers tend to do their homework on their high end purchases now, and uninformed salespeople reflect poorly on the stores they work for. The amazon review system (while it has it's flaws) is amazing and really helps when you're looking for the best product for the dollar, best product period, or just trying to weed out the crap. I actually hate purchasing these sorts of things in stores as I might not know anything about the item I'm looking at, and the sales people are generally no help.
I'm not sure BB will make it, but they do seem to be desperately trying to retool their niche. The return policy is outstanding, the warranties can be great in some cases, and the service related items (geek squad) probably are the only reason they didn't go under. I'm hoping they'll innovate somehow, and don't just wait for the tax equality laws to take effect.
