All of the "cons" you list for the Neo apply doubly if not more for the alternatives you provided. Not to mention the cheap plastic build quality, poor OEM support, horrible screens, etc.
Ryzen 5 AI 340 has a higher multicore benchmark score than the A18 Pro. If you go up to $800 you get the Ryzen 7 AI 350 which matches or beats the A18 Pro in graphics, gets pretty much on par in single core performance, and that SKU has 16GB/1TB in its configuration. If you spend $100 less on the high end Neo with 512GB you get half the storage and lose a lot of I/O and get a worse screen and no replaceable SSD.
USB 3 5Gbps and USB 2 as your only ports are pathetic. Competing systems have more throughput and other conveniences like microSD readers, HDMI, and USB-A.
Inferior battery life, care to send me test data to back that up? Because the Neo is not a star at battery life for medium intensity tasks. It has the smallest battery of any Mac. Early reviews note that screen brightness and higher intensity workloads quickly deplete the battery. It comes with a very slow charging power brick. I guarantee you the physical size of the battery in that Yoga is much larger than what you get in the Neo.
Inferior software: highly subjective. There are over 900 million PC gamers on this planet who can’t play PC games on their MacBook Neo. Windows objectively runs more applications than Mac. Plenty of people I know prefer Windows over Mac.
Cheap build quality: again, Neo has no haptic trackpad, so it’s not that different than a typical windows PC.
Poor OEM support: Lenovo sells parts, Apple doesn’t.
Horrible screens: the Neo has the worst screen in any Mac, the Yoga laptop has a touchscreen OLED. Have you seen the Neo screen in person?
