Hello François,
The iPad uses an ARM processor, not a G4.
The ARM chips were first utilised in the Acorn Archimedes computer range.
They were designed by a partnership of Acorn Risc Machines (ARM),
Motorola and IBM.
The instruction set is very compact, therefore easy to learn. Most
coders built up libraries of standard routines quickly and easily.
I assume that they have not really seen any need for any massive
increase in the instruction set, but I haven't seen anything about them
for quite some number of years, so I really don't know.
Multi-core ARM's now, that would be something else - I predict that may
be in Apple's future.

This is a move by Apple towards independence from chip designers. For instance, I do not know how the G4 iPad chip was designed, but having an "almost" compiler that works independently of the chip must help Apple manage OS X on the iPhone, iPad and Mac.
