Early reviewers are not paid by Apple, but they are all handpicked by Apple to loan them the devices before general release. So generally the reviews tend to be on the positive side. It doesn't mean that they are biased, just they will highlight the good stuff more.

On the other hand, you have websites like Forbes which is well known to talk crap about Apple while displaying obtrusive ads all over the place. Just check out their so-called 'reviews' on any Apple product. They all go along the lines of "Don't get me wrong, the [Apple product] is by all means excellent, but it is actually terrible."

If you are interested in the MacBook Air, you can check out MacRumors forums. You can get honest feedback from real users there. In my opinion, the M1 is without a doubt, a first gen product. Apple may have been planning it for years but real world testing has just begun. Don't expect it to be flawless. However, I believe most of the incompatibility issues will be solved within a year. It is up to you whether to wait and see or be an early adopter.

Done reading the so-called "review" by Forbes. Don't you think the review is not logic at all?

From my experience of buying through Apple Online Store, they will email you the receipt upon confirming delivered to your doorstep. Dated on the day of you receiving the parcel, or some times +-2 days. You definitely wont be able to declare the tax for Y2020 reduction for this purchase.

I noticed people who bought non-BTO MacBooks received their MacBooks early. What do you think of my chances receive my MBA before Christmas next week when I’m supposed to receive between 30/12 and 7/1?
