dropbox, you've been really good to me, but the competition has really got you in the crosshairs....
(and i'm a linux user, which doesn't even work with this [yet?...or google drive], but the competition really has become pretty serious lately).
Something primitive in me starts to kick in when this occurs. I start to question the trustworthiness, validity, and longevity of "other services", which in turn only bolsters who I know best, or even just first. Everything else becomes the proverbial Brand X.
