Is the M1 Pro still worth buying over an M2 Pro or M3 Pro model?

Yes if the work is mostly video editing, photo work or coding. The M1 Pro is slower than the newer chips but still handles those tasks well, and it often costs less on the used and clearance market.

Is 32GB of memory enough for video editing?

Yes for most 4K editing and multitrack timelines. 8K or very heavy effects work benefits from more memory, but 32GB covers typical professional use.

Can the memory or storage be upgraded later?

No. The unified memory and SSD are fixed at purchase, so choose the configuration you need up front.

The laptop, a USB-C to MagSafe 3 charging cable and a power adapter. It does not include a mouse or external display.

Does it have an SD card slot and HDMI?

Yes. It has an SDXC card slot, an HDMI port, three Thunderbolt 4 ports, a headphone jack and MagSafe 3 charging.

How does the 16-inch compare with the 14-inch model?

The 16-inch has a larger screen, bigger battery and better cooling, but it is noticeably heavier. The 14-inch is easier to carry and uses the same chips.
