I wrote a little post to put those numbers in perspective: http://www.upbeat.it/2015/01/16/putting-marcos-numbers-in-pe...

That's not really a lot of money. Going forward, it looks like he might average $20k/month, at best. If he wanted to hire another developer, for example, he really couldn't afford it. Sure, it's nice for now, but it's not a long-term business.

It depends on how much time he spends on this on a daily basis. I am guessing its only a few hours a week now. If you take that view then I think numbers are very good.

This saved time will allow him to do other things and spawn off other interesting projects which is pretty cool imo.

I think it is good info for indies, at least they now know that they need to start alone at the beginning.
