It’s free @ http://www.my2ndgeneration.com/DesktopDownload.aspx of course you can do all of this in the cloud too. But I find bringing the web technologies like handlebars.js and such down to a very responsive native client is extremely powerful. The moment we get an Atom Windows client I will set about adding this as an add-in and literally build My2ndGeneration into Atom.
I signed up for the beta yesterday, hope to get my invite soon. I’d probably be willing to purchase a hosted MAC to get started on this as I’ve done that before.
