But the coding possibilities, and diagnostic with INPA, good stuffs (IMHO). Good thing is e39 and e46 programming updates have more or less stopped after these cars have gone out of production. Not to mention the language differences to overcome in certain areas of the tools, scripts, and volume of updates.
The online, internet has been tremendous source of brain dumps from so many folks, for past few days have most definitely been overwhelming, mainly because of the sheer volume of details on all variations of BMW tools over many, many years.
Sorry to hijack the OP's ramp up, but I too am going from a total zero to try setting up the (latest) Ediabas suite for working on 2003 e e46, for doing usual diagnostic, coding, flashing/programming.
