demo board vs/and/or development board
There has been 'a lot' of talk here recently about the demo board for the propeller. Is this going to be an all-in-one development board setup like the PDB, or is it simply a smaller scale 'development' board?
I get the impression that this demo board will not be as 'complete' as the PDB, is this the case? (It seems appropriate as a 'demo' board...)
If so, will a full scale development board make an apperance sometime soon?
Just what all is going to be included on the demo board?

I also heard through a colleague today that we'll build the USB circuitry into the board just to simplify things (as with the USB-BOE).
To your concern of "the only development board" -- no; just give us a bit of time.

There is quite a bit to sort out if you want to be all things to all people.
I have been thinking that I would like a board for the P8X32A-DIP40 around a core of expandibe [noparse][[/noparse]and adaptible EEPROMs and/or RAMs] and a RTC with battery backup.
Then there is the question of whether one needs a RS-232 interface [noparse][[/noparse]or RS-485].
Of course there need to be a 3.3 volt supply on board, but should there be a 5.0v supply as well.
Of course some would like a Keyboard/Mouse plug and a Video plug. The darn Keyboard takes nearly 300ma of power at 5 volts.
LCDs, 4x4 Matrix keypads, I2C Graphic LCD interface, One-wire buttons, ........ Seems some of these things would be better served by an 'expansion plug' to some kind of personality cards.
