$40/month? It's almost free! And, if $40 really is a big deal, I doubt you would bite at $20 or even $5; you would just do it yourself. Or, at least comfort yourself with the idea that you could.
He said it's too expensive "for such a service", not too much money to spend on anything. If I were to charge you $40/month for a script that shows a user's IP address and nothing else would you still shout "it's almost free!"?
Yes it's not a huge amount of money, but it's enough that I, like the person to whom you were replying, would not pay it - largely because I could code it myself.
Dropbox or Evernote are far more useful to me and far cheaper, and it took me quite a while to bite at their price. This would have to be much much more capable than it appears.
$40 a month for the high end. That said, $40 a month is far from free. To put it into perspective that's about what Github charges for 20 private repositories ;)
