I think this is cool but for me personally it would be so much cooler if it was open-source. Sure I understand they want to make money with it but really this doesn't offer me enough more than my current setup that I would be willing to pay $0.05 - $1.40 per hour. That's up to $33 per day or $1041 per month, (quite) pricey for some background execution and rsync functionality.
My current setup is to use a workhorse server where I set up a samba share for my home folder (so I can edit scripts remotely from my notebook without the git-push-pull dance) and a remote iPython notebook. Both config files are write once and forget and I get 90% of their functionality built in (without the web GUI). Would love to learn about other people's setup though, I am sure mine can be improved.
