Jim Cramer is a big fan of Apple Inc. [stckqut]AAPL[/stckqut], but that doesn’t mean the investor thinks they will be a success in every market. On Mad Money on Wednesday, Jim Cramer expressed doubt about Apple CarPlay, the firm’s in-car iOS platform. Cramer says that Apple will not dominate the market.

The comment came in response to a user question about Harman International Industries Inc. [stckqut]HAR[/stckqut]. The firm makes in-car systems right now and has a market cap of $8.7 billion. Shares have fallen by more than 13% in the last month, and one investor was looking to find out why. Cramer said it all came down to Apple.

“Problem is the Apple car play. People think Apple will take over car infotainment. They are wrong and you should stick with Harman,” he told the caller. That’s far from negative on Apple’s CarPlay, but it does present some lack of faith.

Many Apple [stckqut]AAPL[/stckqut] fans, investors, and analysts were surprised when The Wall Street Journal reported Cupertino has shelved its plans to bring a ultra-high definition television set to market over a year ago. According to “people familiar with the matter,” Apple could not differentiate from TV sets on the market enough with compelling, breakthrough features in order to justify its entrance into a competitive market.

Among Apple analysts, the news that Apple shelved its television plans came as a surprise to some and confirmation to others. Count Piper Jaffray’s Apple analyst, Gene Munster, among the surprised, has perhaps been the most vocal about Apple’s TV plans, warning fans that Apple TV was coming to market as early as 2011. In an appearance on CNBC’s “Squawk Alley,” Munster appeared downright solemn with his mea culpa: “This is a tough day for me. It’s a hard reality to accept, and I think that is the reality of it: the TV is on hold.”

Others, myself fortunately included, thought Apple’s plans for a television would not come to fruition for a simple reason: gross margins. Simply put, the television business isn’t as lucrative as Apple desires and it appears Apple could not find enough truly differentiating features to justify higher-cost, premium TV sets. For Apple investors, that’s important insight into this company.

Orders of Apple Inc.’s [stckqut]AAPL[/stckqut] iconic Watch have been disappointing and even become stagnant, says online consumer spending tracker Slice Engine.

Orders were brisk from the onset, far ahead of supply, and seemingly on the up. Inventory quickly sold out. Issues with the wearable’s taptic engine led people to believe a healthy supply chain was the only barrier to continued sales.

With the Apple Watch having been launched barely a month ago, many are already comparing Apple’s new smart wearable to the existing ones in the market. There is no doubt that Apple [stckqut]AAPL[/stckqut] has shaken up the wearables market, and increased interest in it as well, but the Watch could hardly have been expected to instantly break barriers. It turns out that a study undertaken by investment firm Robert W. Baird & Co., spotted by Apple Insider, supports the argument that Apple has not yet monopolized the market, although it is indeed gaining ground.
