Well spotted: 1600 for only 16 GB (soldered) RAM. Soldered would be fine, if it was 9600 MT/s and 32 GB RAM (tho, in times of LLMs and data privacy, it's time for 48 and 64 GB RAM configs). Not saying it's an alternative for everyone, but a MacBook Air 15 (15.3") with this config is available new at just a bit more or at even lower price directly from apple.com/Apple Refurbished (Air M4 32 GB RAM).
Also, it's 1600 for no GPU and only a slow 4-core Intel Arc iGPU.
Not sure what's worse, the soldered 16 GB RAM or this iGPU.
NBC, switch to Steel Nomad, it's the official successor to Time Spy and makes the performance comparison to the Air directly possible:

2026 Air M5: score: 1070
Intel Arc Graphics (same 4-core, only the 12-core is allowed to have Arc in name): score 660
The Macbook Air is 60% faster while having no fan (and is lighter, slimmer, arguably a better display, ..? The XPS wins in battery life by the looks of it?).
