First of all, no idea why you were expecting Apple to shove an SD card slot in the MacBook Air. It hasn’t had one for the last several generations, it’s not coming back.
Because they finally came back to mind and put it in the Pro. There is more than enough space in the new form factor. For a super portable device, like the Air is advertised, having to use dongle for every single **** is more than annoying.
The M1 MacBook Air from 2020 has the exact same estimations, 15 hours of web browsing, 18 hours of movie playback. So… no decrease.
The MacBook Air M1 was (is) advertised with up to 20 h of battery life. Check the numbers.
Sure it’s an extra $200 than before, but with that $200 you’re getting a bigger and brighter display, four speakers instead of two, a much thinner design, a faster processor, a 1080P webcam, MagSafe with fast charging and… Did I mention it was thinner? The MacBook Air living up to its name.
Following your weird reasoning, the MacBooks should increase in price every year by 20-30 %, for just getting
regular hardware upgrades and minor new features. The exact opposite has happened for the Air after it was introduced. Now, you get the
regular hardware upgrades for completely outdated hardware they still have used, cf. the FaceTime camera, for an enormous price increase, cf. last generation of MacBook Pros. In former times, prices only increased if there were dramatic changes in the hardware, like for the first Retina models which had - at least - some reasoning.
Now Apple seems to follow your absurd reasoning: bringing back common features like the MagSafe, I/O and finally introduce the 14'' screen etc. dramatically increases the price with each generation, although it's just regular hardware upgrades in 2022. On top: we sell the
almost 2 years old, outdated hardware, Air M1, at the
same price tag as before? 10 years ago, Apple was famous for having stable prices, which were of course higher than the competition, but justified because the money went into the development of new, "amazing" products.
Funny side remark: The original US price for the Air is $1199, that is (today) 1121.82 EUR; i.e. including 19 % VAT in Germany that is 1334.97 EUR. But in the Apple store the Air costs 1499 € (!). That is a surcharge of 164 EUR = 12,3 %.
Maybe they don’t need the big bulky machine but still want the latest and greatest.
Because the MacBook Pro 14'' is 300 g heavier (oh noe!) and 0.4 cm higher. So "big" and "bulky" in comparison.
