I think you nay sayers are all missing the point here....
First of all, not everyone lives right next to a major electronics store such as Best Buy, or Circuit City. The whole point is this is the get the iPod into the hands of those people who don't already own one and don't live somewhere around an electronics store.
Apple must plan on selling a TON of these iPod Shuffles if they want to sell in WalMart, because they will certinaly sell.
What this will do is also get Apple's name out to the people who aren't computer oriented and so they may at least think about buying a Mac.
That being said, if the iPod shuffle is doing real well, and Apple has caught up on Mac Mini orders, I think Apple should sell the Mac Mini in Walmart too. Apple's market share is diminishing. Its less than 1% worldwide. Its something like .8%. So in other words, out of every 100 computers sold worldwide, not even 1 of them on average is a Mac.
Apple needs to do something such as sell the Mac Mini in WalMart stores. This will further get Apple's name out there as a computer company, and NOT just the creators of the iPod. Believe it or not, there are still people out there that know of the iPod, but don't know that the creators of the iPod also make computers.
Now, in order to sell Mac Mini's in WalMart stores they need to find a way to market this really well or else it the Mini will just sit there and gather dust. The so called scumbags (no offense to anyone) that work in the electronics dept of WalMart will know nothing about it, so they will put it down as something thats not compatible with PCs, there's no software, no peripherals, etc, all which are not true as we all know. But you have to get that into people's heads, that Macs are just another producer of computers. I think this would be the best thing that Apple has done to increase their marketshre in the computer industry if they go ahead and do that. All they have to sell is the Mini itself. No Apple Cinema Displays, no iMacs, or other computers, nothing else. If there was one thing they could sell, its the keyboard and the mouse.
Software is another issue, but WalMart can increase its software dept without any problems and offer the basic Mac apps such as Office, Print Shop, and maybe a few games. Just the typical software titles that aren't standard on a Mac. WalMart doesn't offer much for software anyways except for the $10 rinkydink titles that sometimes run on both platforms.
It shouldn't matter what people think of WalMart. If the 350lb fatass moron down the street buys an iPod Shuffle and/or a Mac Mini thats the friggin' point of doing this. Just becuase WalMart treats its employees poorly, and Welfare people shop there doesn't mean its not suitable for Apple. It doesn't destroy Apple's name, it gets their name out there to others who don't have a clue as to what Apple is. If Apple feels any pressure from WalMart on anything, they'll pull their products right out of WalMarts hands, just like they did with Circuit City, Best Buy, and Sears and it will be a loss for WalMart, not Apple. Apple is in control here, not WalMart.
So I other words, I think this is something Apple should do. People need to stop thinking that Macs should only be sold in expensive electronic stores. Macs are for everyone, and everyone should have the opportunity to look at them, use them, and most of all, buy them.
