The Macbook Air competitorship argument is an interesting one, as displays are a critical component of the comparison.
On one hand, the review unit has only a WUXGA resolution. Just as, in the days of old, 1366x768 ultrabooks with bad TN panels could not be seen as level with the 1440x900 Air with a better TN, we cannot compare the 1920x1200 in this review unit with the 2560x1664 of the MBA 13. On the other hand, it does offer 2880x1800, and both display options are OLED in comparison to the globally-backlit (not MiniLED) IPS LCD of the Macbook Air.
In any case, this 1920x1200 and the Mac's 2560x1664 displays are both burdened by a 60Hz refresh rate. Only the 2880x1800 option here resolves that with its 120Hz. Moreover, we don't know how the upgraded panel will affect battery life, which is its own point of contention.
At least we're well ahead of those 768p TN days. We can rest easy knowing that every display in question here is respectable.
