I have worked on embedded systems for 30 years and I have the same problem.
My view, is that if the system can't run games, it's not an embedded system ;)
That said the Altera 'SoC's are interesting. They are expensive however they cut down development risk. That said, a $12 ARM processor and a separate $15-$25 FPGA will probably do the same job. However if you don't know what you are doing then clearly the Altera 'SoC's eliminate that risk.
And divide-by-zero? Multiplication is repeated addition, division is repeated subtraction. The concept of divide-by-zero simply means that one can subtract zero from a quantity forever without changing the value of that quantity.
So why do computing machines have such a problem with this?

You got to use eight? Pfui, I only got 6. The Univac 1100 series had 36-bit words, so you could fit six 6-bit ASCII upper-case characters in a single word and compare names as integers. Watch out for negative zeroes!
On the PDP-11 you could fit 6 characters in 32 bits. Magic, you ask? Yes indeed, a magic spell called DEC RADIX-50 which encoded 26 upper-case letters plus 10 digits plus a few punctuation marks into a number from 0-39, and then multiplied the first character by 1600, the second by 40, the third by 1, and added them all up. So why "RADIX-50" instead of 40? Well, we PDP-11 dudes always preferred thinking in octal :-)

Max , think yourself lucky - i remember the days when i was tasked with creating a world out of emptiness - no where to store variables - and i considered myself to be lucky.
@Andrew: Is the definition of embedded in the context of embedded systems that heavily varied?
Oh to be young and innocent once again. If the definition were so simple, then experianced engineers wouldn't have so much trouble saying "This is definatly an embedded system while that certainly isn't."
So, we'll be seeing you at the chat on Friday 11th July, right? LOL
An entire debate? Is the definition of embedded in the context of embedded systems that heavily varied? If it's not a relatively specialized, computerized system that is often embedded in a bigger system, then I have been misleading a lot of people over the years.
@kfield: I am still having trouble over the definition of embedded. :-)
Fear not Oh leader of men (and boys) ... legendary embedded guru Jack Ganssle and yours truly are going to be having a debate about this very topic in a live "Radio Show" starting at 2:00pm Eastern on Friday 11th July -- after we've talked for 30 minutes, everyone else will be able to join us in an online chat. I'll be posting a blog about this in a day or so when it's all set up in the system.
@Wnderer: I read documents coded in acronyms and write code documented with LongVariableNames.
