I have a bunch of 2in1s for my parents and my own needs: MSI 13 Modern; Asus X13 Flow, Asus 2022 X16 Flow, Asus 2023 X16 Flow now.

For the smaller laptops :

Heat issues - small package : going to over heat while gaming, hard to impossible to find a dedicated GPU equipped model.

Battery life - smaller chassis - hard to find large battery capacities

Storage issues - smaller then usual M.2 drives required. The various Lenovo models will need M2.2242 drives which are slightly more common but trying to find a 4TB M.2 2230 drive is impossible or super overpriced.

Soldered RAM issues - The smaller laptops would have soldered RAM on it, if you can live with what issued then good for you but if you were trying to do engineering work forget it or needed to pay much extra for 32GB.

I think i shall pass on any WD based SSD for a while until the hardware faulted SSDs work themselves out of the market.

Dewalt usb c PD kit. Provides 100w output power for devices. Uses modular tool batteries as the power source.

Imuto 160w usb c PD power bank. I use this on planes for keeping the phones charged.

Figure out what you need to do with the laptop at school. For some items a Mac maybe helpful with the whole intergrated IOS setup but will hurt your wallet. They currently have the best battery life on laptops while Windows can certainly get more performance out and have wider software usages.
