Second hand M2 pro or wait for M4?

More parameters of the M4 have been disclosed. According to the sale price of the ordinary M2 macmini, the current price of the second-hand M2 Pro macmini should be lower than the price of the ordinary M4 version of the macmini. Looking at the CPU parameters, there does not seem to be much different between the M4 and the M2 Pro. The paper parameters of the M2 Pro seem to be higher. In addition to the difference in size of the machine, the ports are also the same. There are also 4 Type-Cs available, and the M2 also has two more A ports, so you can plug in a mouse and keyboard without a hub. Furthermore, the M2 capacity expansion technology is also more mature, and it is suitable for more storage chips. When expanded to 4T, it can read to 6000M per second. https://i.imgur.com/Tjn1psD.png https://i.imgur.com/9MS2rhF.png
