hi, great question. we have to start with something and while the RP2350 is not going to beat a 600mhz m7 it is much less expensive, fast to get, has lots of nifty support libraries available, and will definitely do better than the teensy 3.2 which many folks loved so much (and was discontinued during the chip shortage). this is also a great time to add things that we always wanted in the teensy: SWD debug, built in 8 MB storage, lipoly battery charging, open source bootloader, open hardware design. stuff like CAN is supported via PIO (
https://github.com/KevinOConnor/can2040), as is USB host on any two adjacent pins. M33 has FPU, and the dormant/RTC mode for the RP2350 is 10uA (see
https://www.tomshardware.com/raspberry-pi/raspberry-pi-pico/...). other 'teensiriffic' things like NeoPixel DMA support is well supported by PIO on the RP2350. as well as I2S audio.
as for the bootloader chip: we don't want to trade one closed-single-source component for another. if we're going to make something it should be fully open source as much as we can!
finally, for teensyduino libraries that you love: there's no reason they cant be ported (we did an audio port for the samd51) - which specific library are you referring to?
