Really? Real "computer stores" still exist? Perhaps where *you* live (let me guess, Silicon Valley), but here, nothing that constitutes a *useful* location. Sure, there are the storefront shops that are little more than places to drop-off your virus-laden Windows machines to be scrubbed; they might have a handful of overpriced and/or non-useful video cards, perhaps an anemic hard drive or two (usually priced 3x what they're worth). And forget WorstBuy or RadioSlack; one never *was* intended to be much more than an appliance store, and the other has turned into little more than a crappy cellphone store (ANY parts, computer or non-computer, have been pretty much abandoned).

When you had proper computer stores, it was easy to quickly find parts to fix somebody's home or small-office computer; just pick up a part on your way home from work, it could be done right away. Not even a matter of "instant gratification", more a matter of fast repair and getting someone back up and running sooner. So much for the hype of "Just-in-Time" supply. And perhaps you'd rather use cash rather than running up your credit card debt. Nope, can't have that either.
