I’m at an IBM event this week, and at dinner I had what has been an increasingly frequent experience.

It used to be that attendees at these events gushed about the new Apple gadget they were carrying, and anyone who expressed reservations seemed out of touch with the group. Much like talking about religion or politics from the minority position at the dinner table, bashing Apple was one sure way to ensure everyone thought you were an idiot.

But last night, instead of showing off an Apple device, another guest showed off his new Samsung Galaxy S III phone, which led to more chatter about my new Microsoft Surface tablet. It spiraled into an “everyone dump on Apple” event, and by the end of the evening, Cupertino’s sole defender seemed to be considering other options.

This may be anecdotal, but I’ve seen the same event played out several times recently among analysts and other influencers in the tech space. It makes me think Apple’s image is changing, and the firm’s products are losing their magical edge.

Samsung’s anti-Apple marketing

The blemish on Apple’s spotless image didn’t just appear there; Samsung helped etch it into the glossy white plastic quite intentionally. Its excellent marketing campaign has attacked Apple’s image on three vectors.

The first is questioning Apple’s leadership. Samsung’s ads paint Apple’s “upgrades” as features the company accidentally or intentionally left out of prior products (larger screens, 4G radios), or obvious improvements (headphone jacks on the bottom). In some cases, they also point out where Apple still lags behind the curve after launching a new device, like the lack of NFC in the iPhone 5. Samsung wants to depict itself as the innovator Apple is struggling to match.

Second, the campaign raises the idea that Apple fans aren’t smart consumers. They’re depicted slogging through long lines waiting for their technology, and getting unreasonably excited about aspects of the product that aren’t exciting. In fact, the not-so-subtle message is that Apple buyers are kind of dense.

Finally the ads build on this dense concept by showcasing Apple users as people you wouldn’t want to emulate: Your parents. Dorks. Clueless hipsters. This is designed to strip away the prestige that Apple products typically carry.

For all its mocking, Samsung actually copied Apple with its first smartphones, but has since diverged, trying to drag away the perceived market leadership with it. The Korean company waged a similar type of warfare on Sony in the television space, which was once the clear leader. Samsung first emulated Sony, then partnered with the company, then took the market away. Sony has never recovered. Granted, Sony had additional issues that complicated things, but the plan worked, and Samsung appears to be following the same playbook with Apple.

Microsoft Surface

Samsung isn’t the only company slinging mud on Apple’s image. The Microsoft Surface tablet is doing relatively well, and Apple’s efforts to disparage it have largely been ineffective (at least so far). It appears to have been designed specifically to make the iPad look wanting in comparison.

As I write this, the Surface is still generating lines, but the important part is it looks both more advanced and more unique than Apple’s offerings. This impression dovetails nicely with Samsung’s efforts, because while the two companies aren’t aligned on products, they are aligned on a common message: Apple’s offerings don’t convey status anymore because they appear to be bought by stupid people.

The too-soon iPad 4 and too-expensive iPad mini

The third leg on this this ugly three-legged stool comes from Apple itself. Its latest launch even showcased an array of different products under one roof, a “big bang” event that trivializes individual products. Firms like Compaq were famous for this approach, but Apple has avoided them like the plague since Steve Jobs returned in the late 90s. Worse, the new iPad made buyers of the old version – launched only back in March – look stupid.

Meanwhile, the iPad mini was priced well out of line with competing models, with inferior specs. When Steve Jobs launched the iPad, it was the lowest priced tablet from a major vendor in its class, and since then, it has remained price competitive against the alternatives. The iPad mini is priced at a 65 percent premium, but lacks the same high-quality displays found on far cheaper competitors. Smart people would probably not buy it as a result. I wouldn’t be surprised to see Apple discount it significantly once initial demand falls off, leaving early buyers upset and looking stupid yet again.

Destroying Apple’s brand

Apple’s strongest asset is the power of its brand, and the historically valid belief that Apple products are purchased by smart people who are well regarded. This asset is being systematically destroyed, overtly by Samsung, covertly by Microsoft, and stupidly by Apple. Apple is not effectively defending this incredibly valuable asset, and the end result will likely resemble the company that existed before Steve Jobs’ return. That also means a market less dominated by Apple. Since I’m writing this on my Surface Tablet, I’m thinking this may turn out to be a good thing.
