I'd be especially interested in lots of digital and analogue I/O

My background is that I've always been happiest with naked machines
so have not investigated the world of built-in OS and language before.

I prefer the raspberry pi to arduino as it has IMO a lot more ready made
projects.
Arduino is good if you are happy with C and C++, the Pi gives you Java,
python... in fact just about any language you can name.
Arduino wins out on peripherals, the 'shields' provide a lot in
connectivity with the real world.

If you buy a pi then within a few minutes of taking it out of the box
you can have a wspr beacon up and running (a bit longer if you want a
nice clean sinusoidal signal). Great for testing your antenna and the
propagation.

===========
1) The Arduino is a microcontroller circuit board with input and output
pins ,but cannot be loaded with an Operating System .

2) The Raspberry Pi is a computer capable of being loaded with an
Operating System . It also has a number of I/O pins.

NB ; The Pi version 3 ,model B ,recently launched ,has an ARM quad
processor 64 bit and 1 GB RAM .........a lot of computing power for
GBP 30.- ,.....fantastic !

Given the OP's request, I would recommend a TI Launchpad (~$15) using an
ARM Cortex-M4. They are good processors, much more capable than the
AVRs on the Arduinos. Of course that is not the only issue. Likely
more important than the details of the board or chip is the development
environment. I've not Arduinoed myself, but my understanding is that
line of MCU boards has a lot of software and there is no shortage of web
based info and references.

I don't use C or Python myself. I use Forth which is available for the
Launchpads. I find it much more interactive and tuned to the needs of
hardware oriented users.

If you like the rPi, the 2 or 3 are good development platforms and the
zero would be a great embedded board for only $5. I haven't been able
to buy one yet. I don't want to pay $7 shipping for a $5 board and the
local (to a friend, not me) store is always out of stock. Seems they
aren't making a lot of them. I expect I'll have a 3 before I can get a
zero. There is a group for the rPi, comp.sys.raspberry-pi
