i use a Mac solely for music...i run protools and don't have that computer on the internet at all...the only issue i have had is i filled it up with music...then i got an external hard drive and transferred all those files over to there...no problem since, when i fill that up i'll just get another...well on my way to doing so. some folks back up to two externals for safe keeping...not a bad idea i suppose...i think the most important aspect is...does it work for you? will it make your creative process easy, can it interface well with collaborators globally?can you pull your parts off and send them? can you get theirs and add to them and send them back? that's where all this is headed... so good luck...be well... see ya ...moker
