Not necessarily a historic peak. Also, Apple can't guarantee where exchange rates will go. In the case of the 16e, they may have added a "buffer on top" because the converted price at the time was above $850 CAD (using my previous figures, somewhere between $851 CAD and $881 CAD depending on when price was set) so they went with $899 CAD.
In the case of the Mac mini, the converted price may have been below $850 CAD at the time (using my previous figures, somewhere between $809 CAD and $833 CAD depending on when the price was set) so they went with $799 CAD.
Had the exchange rate put the mini price above $850 CAD at the time (last October), it may have been priced at $899 CAD just as the 16e is. Conversely, had the exchange rate put the 16e price below $850 CAD at time (this month), it may have been priced at $799 CAD just like the mini. However, that wasn’t the case as demonstrated above.
As I said, this is just a theory on my part.
I get what you are saying but it still doesn't add up to me.
Mac mini Announcement date: October 29th. 2024
Xrate on Oct 29th = 1.38894
599.99 x 1.38894 = 833.35
They chose to go lower at 799.99 and without buffer while the Xrate was trending to go upwards. Even if they used the X rate from the month before, 1.35163 on Sept 29th, 799.99 would still be lower then 810.96, and without buffer.
16E announcement date: February 19th, 2025
Xrate on Feb 19th = 1.42096
599.99 x 1.42096 = 852.56
They chose to go substantially higher at 899.99 while the Xrate is trending to go downwards. A month prior on Jan 19th, Xrate was 1.44792. 599.99 x 1.44792 = 868.74. They are still way higher at 899.99.
I only use the month before rates as a guess. As the only thing we know is the announcement dates and those don't match either. If they used your logic, 16E would be 849.99 to 869.99, and if they used M4 Mini logic, most likely 769.99 to 799.99. Like you say, and I agree, all a theory based on speculation of course. Once the rate goes down to it's normal level, these will be a better buy for Canadians that shop in the US.
So yeah, up here, I feel it's a bit of a rip off for no reason. But ultimately, we will see how the sales go here. I'm guessing Apple will allow this sku to be heavily discounted if sales are mediocre or worse by carriers. Or it will hang around for 3-5 years like the SE without any or much changes and the MSRP will go down as well. Unless Apple chooses to refresh these every year as well, which would be interesting to see.
