The vast majority of individual MBP buyers are not buying a new one every year. I’d wager less than 1% are annually upgrading a several thousand dollar laptop. Institutional buyers, which I work for one, are ok with a year old model, that is frankly still one of the best laptops on the market. Heck, they are still purchasing 2 year old Dells. Those that didn’t purchase already and don’t need will wait for a refresh. Those that need a new laptop right now, will still be getting a great laptop.Macbook buyers aren't a single, monolithic entity. There are some who buy a new one every year. Others are on a different cycle, so the lack of a new model this year creates a bit of a problem for them... buy a year-old model, or wait until next year to buy the new model.
Do you have any data to back up that claim?
That all being said - Apple will ship them when they’re ready. I work in supply chain and it’s still a mess. TVs that were announced at CES were released later than usual this year. Plenty of other products that rely on chips has similar issues. This article makes it seems like there aren’t really any external factors at play. The effects of the pandemic will take at least another year to clear and frankly, the Covid outbreak in China shows how much we still have to go. These aren’t normal times and this stuff already operated on extended time horizons without the pandemic.
