The question arose because his message doesn't appear either in the 
conversation/email thread 'here', nor on the Archive. Perhaps not sent 
to the list?

As I understand it, posts to 'the list' may be made at comp.lang.python 
or by email. Once on the server, messages are reflected back to both. 
Thus, Thunderbird is not set-up to use the newsgroup and keeps 
complaining at me when it's asked to reply to both. So, all 
contributions (from me) enter the server via email.

Adding a display to the Pico-W is my next project... After that, gyros 
(am thinking it may not go so well, on balance... hah!).

The Pico-W impresses. Its built-in Wi-Fi/Bluetooth capability makes life 
a lot easier (inside building use).

Apart from the earlier comment, my biggest frustration has come from the 
lack of facilities in Thonny compared with PyCharm - but will pick-up 
skills there, no doubt.

Conversely, (to having a separate radio-chip) I think I prefer the idea 
of being able to connect the Pico to whichever sensor(s) is/are 
actually-required. However, this is applied use - not learning or 'playing'.

Whilst agreeing with the "easiest way to get started" claim, it probably 
also leads to the assumption that it will (later) be easier to run out 
of capability. Hence, that MicroPython would be the better professional 
option - assuming one already knows Python.

Yes, a degree of 'comparing apples with oranges' - and a 
continually-moving target!

No, out in the real-world, the Pico 2 is still vaporware.

True.
Hence the question.
Thanks for the comments!
