How we choose

Source: Amazon.ca catalog, checked on 12/11/2026.

Lowest price seen for the product on Amazon.ca, delivered to Toronto M5V 3L9, on the day it was read, before GST/HST. The model is the brand plus the name of the laptop; the versions go in the table. The price range, the median and the position use only models with a score; the price comparison looks at models whose score is within 0.5 points.

The spec score doesn’t measure real-world performance or durability, and the strong or weak point reading is just a comparison of numbers, not a buying recommendation.
