If you pay for Dropbox what exactly are you paying for? Software to communicate with S3?
I'll accept that the software (python+rsync+an icon) is arguably "value added", but for the paying Dropbox user, what they are getting is still S3 storage.
Am I missing something?
(another vote for a log scale (or something equivalent, like a separate "units" that sets the scale to 1s, 10s, 100s...). also, the tick marks should be on reasonable, round values)
But this is kind of like saying iOS is just an expensive closed variant of FreeBSD.
Since I'm not drawing a salary from Dropbox's marketing division, I'm not going to go in depth here but I'll just say that Dropbox can be used easily and efficiently by normal people who have never seen a command line. Whereas your home brew python+rsync scripts can only be used by nerds like us.
Maybe you discover the sarcasm in my comment. ;)
