The thing about a 'Swiss Army Knife' is that it doesn't do anything well. Remember the old saying, "Jack of all trades, master of none". In music, as in life, there are no shortcuts; someone (Gary?) said "it can take months to prepare an arranger keyboard for a gig" - well guess what; it takes YEARS to prepare an acoustic piano for a gig. So yeah, there may be a 'lazy' aspect to it. Just sayin'.

But here's the thing. Those that use them are going to defend them to the death; those that don't are going to pooh-pooh them to the death. Funny thing is, nobody's right and nobody's wrong. If it works for you, as Tony says, "who really gives a shit?".
