The CPU in itself should be pretty good by modern standards: https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+Ultra+9+...

Her issue is not the form factor. Is it the RAM ? did she activate all the marketing apps ? Is a bitcoin farmer running in the background ? I don't know, but it's worth looking into it.

For comparison, I have at hand a Surface Pro 8 that should be 3x slower than hers on sheer CPU benchmarks, and I can throw any run of mill task at it (do the taxes with 3~4 word documents, Excel, dozens of tabs in firefox and a call session in the background) and it's fine. It will burn trough battery life within an two or three hours under that load, and yes the fans will be running, but I have no issue of having it crawl when unplugged.
