If you frequently work with external displays, it's worth noting that Apple's just-announced M3 MacBook Air models support two external displays – one more than the 14-inch MacBook Pro with the same M3 chip.
Launched last October, the 14-inch MacBook Pro with M3 chip simultaneously supports one external display with up to 6K resolution at 60Hz.
In contrast, both the 13-inch and 15-inch MacBook Air with M3 chip support one external display with up to 6K resolution at 60Hz, and two external displays with up to 5K resolution at 60Hz when the laptop lid is closed, also known as clamshell mode.
Given that the machines use identical chips, it could be that the additional external display support on the MacBook Airs has been made at the software level. If so, there would seem to be no reason that it could not be added to the M3 MacBook Pro in a future software update. However, it could also be a hardware-based change, and we might not know for sure until a teardown is performed on the new laptops.
The new M3-powered MacBook Air models start from $1,099 and can be pre-ordered on Apple's website, with availability beginning on Friday, March 8. The 14-inch MacBook Pro with M3 chip starts at $1,599.
