Are you a Windows user?
It seems like most Tumblr users are Mac people. But there must be some PC/Windows Tumblrs out there. If you are a Windows user, can you explain why in a reblog?
In then end I’m using the OS to do something else. The best operating system on the planet wouldn’t be noticeable; it just stays out of the way and lets you do what you need to do.
I use all three OS flavors (Windows, OS X, Linux) pretty much equally. Each really has their strengths and weaknesses, but in the end there’s a lot less to OSes then people would have you believe. I’ve got dropbox set up to automatically sync my data between each installation, and the day’s choice of OS depends more on a coin toss then anything else.
