I can also see Ghost becoming a decent competitor for Wordpress. For the purpose of blogging that is, because I remember reading somewhere Ghost didn't have any intentions competing with Wordpress.
I had started running into problems with generating my Octopress blog when I messed up my Ruby install. Also, although it was a good thing at the time, I didn't like not being able to write posts without my MacBook to hand.
Ghost is nice, fast and easy to use. Static pages are really going to make it even better.
I have a setup that immediately publishes my blog somewhere when Github receives a push (working through travis). I seperate two branches, one gets pushed to a staging area, one to the live site. I do the touch-up when I am at home. I usually want to write anywhere, but not necessarily publish anywhere.
In the end, I just write my posts using any text editor I can find, be it Githubs direct editing. On the train or in a flight, I use an iPhone with a bluetooth keyboard (it works surprisingly well, except the odd looks) or my notebook to write the posts.
