In addition to the raw compute power, the HP laptop comrmes with a:

• monitor
• keyboard/trackpad
• charger
• windows 11
• active cooling system
• enclosure

I’ve been looking for a lapdock [0], and the absolute low-end of the market goes for over $200, which is already more expensive than the hp laptop despite spending no money on any actual compute components. And, at that pricepoint, the lapdock will also be of significantly lower quality than the cheap hp laptop.

Granted, this is because lapdocks are a fairly niche product that are almost always either a luxury purchase (individual users) or a rounding error (datacenter users)

[0] Keyboard/monitor combo in a laptop form factor, but without a built in computer. It is intended to be used as an interface to an external computer (typically a smartphone or rackmounted server).
