I was wondering if a PIC16c84, or any PIC was powerful enough to
be used to make a sort of a laptop.  The Z80 is used in Nintendo's Gameboy,
and the TI-85 Calculator, both of them are fairly powerful.  How does the
PIC compare?  I want to make a simple laptop with a 320x200 LCD, qwerty
keypad, and a task switching graphical operating system.  My main concern
next to speed is memory, would I be able to use any external memory with
the PIC microcontrollers?  Would something else be better suited for this
type of project?

                                                Thanks,
