Ignorance is bliss - you'd have been happier if you never knew :-)

Since Scott has already posted a link, I think the key thing to know is 
that it is one of the most brain-dead of all the brain-dead 8-bit CISC 
microcontroller architectures around.  It makes the 8051 look smart.  We 
are talking single register, banked ram and flash/rom access, separate 
memory spaces for code and data, an assembly language that reminds me of 
microcoding rather than assembly code, hardware return stack of limited 
size, very limited and highly inefficient indirect memory access instead 
of pointers.  There have been a number of C compilers for the chips, 
each of which has its own range of non-standard features, extensions and 
limitations necessary to get usable results out of the device.  The 
official compiler supplied (at a high cost) by the manufacturer at one 
time supported structs, and arrays, but not arrays of structs or structs 
containing arrays.

On the other hand, the manufacturer never stops making devices - even 
when they are decades out of date, you can still buy them.  That kind of 
long-term availability is very rare in the business.

And the microcontrollers are incredibly robust.  I've seen PIC 
microcontrollers rated for 85 °C run happily at 160 °C.  Short-circuits, 
over-voltages, and all kinds of hardship that would kill a lesser 
microcontroller rarely bother PICs.  And they are popular with hobby 
users as they are available in packages with big legs that are easy to 
solder at home.
