To add to what others have said, the cost to manufacture the 450X remains the same. Earlier, the 450 Plus had a reduced price despite having the same hardware as the 450X to create an easier entry point for newer customers who didnt want the flagship 450X.
What we did say in the Open House was that due to COVID we had more time to evaluate how we could further differentiate the two versions, 450 Plus and 450X, and see if we could lower the entry point further. We were able to reduce the price of the 450 Plus, by manufacturing it exactly to its spec instead of just differentiation by software.
To be clear, the spec of the 450 Plus remains the same as what we had announced back in Jan. Just that it’ll now have a slightly smaller battery, and a few hardware changes, allowing for the price reduction.
