[sdiy] Why transistors arent square!

[karl dalen]

One thing that have puzzled me over the years, why arent all
small signal transistors made in flat square packages? 
(some few Japanese are).

This cumbersome half-moon shaped packaging are drag!
If the packages had been square, stacking and leveling to 
cooling or heating surfaces would have been a breeze!

The SOT23 are allready rectangular so why not the TO92?

Another thing, why arent there any OP amps that behaves like 
the inputs of the OTA? It would have been a pleasure to have
OPamps that summed into virtual ground on both inputs and
gain settable by either input or the normal minus input
in regular feedback!

Or why not a OP amp that had one input and one phase select input
so one could switch the phase responce of the input/output, would have 
been great!

Where have the innovation in todays semiconductior labbs gone?
