In fairness, many of these will end up in consumers hands shortly after a bit of additional value-add. On the bare-bones side, that's things like JLC PCB stocking them for pro-hobbyists to get custom low-volume PCB's made with them. A bit higher up the food chain, mere tinkerers could expect to find more form factors of fully ready-to-use boards available at microcenter/ailexpess/amazon/sparkfun/etc.

For mere hobbyists, adding network connectivity will be the biggest hurdle for most of their projects, and hopefully some of the microcenter (et. al) options will provide options. It doesn't have any on-board solutions for this (unlike, say an STM32F207 which has low-level ethernet capability that just needs to be broken out to a physical interface).

Generally though I think most networking solutions for the RP2040 will max out at 66.5Mbps max theoretical throughput, because this is the limitation of SPI interface when the RP2040 has its system clock set to 133MHz (perhaps a bit more throughput is possible with overclocking).

Note that the dual Cortex M0+ cores have some (serious) limitations, namely: No floating point math (although the compilers usually do a pretty decent job of letting hobbyists forget this!). No Embedded Trace Macrocell or Program Trace Macrocell for debugging (only Micro Trace Buffer). Only 4 breakpoints and 2 hardware watchpoints.

It's important to truly understand the hardware limitations as much as possible to avoid issues caused by things like interrupt priority inversion[0].
