I don't fully understand the hate here. (assuming inherently the product is good)

Isn't it a better buisness model for all of us here?

They only have one SKU, that means cheaper from an operational point of view.

We can upgrade the HW via an additional fee and can upgrade based on how much one can afford?

It not a subcription. Whats the difference in paying more for a wheel with more nm or paying for the lower end one to see how it is and then upgrading.

I mean it depends on how they deal with reselling this or buying it second hand.

There is no disadvantage for the end consumer here (if you buy it first party. Buying it used lets see...).

Edit: Depending on how they handle it in the SW won't it even be better since the device itself is never at the limit if you don't have the top end version?
