I do embedded systems WITHOUT a logic analyser. You can do about
99% of what you need to with a monitor and an oscilloscope. The
logic analyser (or emulator) is the big gun for the really nasty
bugs.
My own policy on embedded development is to pick one or two
processors and get to know them inside out. Then you can better
estimate the time required to do something because you have
some history.
Also, remember to pick a new "up and coming" processor so that your
skills continue to develop.
Sorry for the off topic post. Comments anyone - and lets's not start
a big Mac/PC type flame war, let's trade horror stories instead :-)
