came back to say exactly that, teh first compile+upload is slow (almost 2 minutes), so anyone benching the setting shouldn't despair after just one.
i usually don't make it through that many uploads before some kind of com error (eg. loses port, gets stuck in upload) occurs, but they are generally easy to remedy. does make a crucial difference to teh dev experience. multitasking.. i recommend the traditional compile procedure.. pack a bowl and wait it out
