Thanks! that's exactly what I'm doing every day, I use headphones too and plug/unplug them very frequently. I also never shutdown the mac, I just put it to sleep by closing the lid.
I've been doing the same for years with the old MBP (regularly coming to 30 days uptime without any itch) and always considered this the best feature (bulletproof sleep) that keeps me from going back to linux.
PS
Ironically enough, just after posting my first comment the mac freezed up again...
I've been recently (December) upgraded to a similar rMBP (2GHz i7, 16 GB RAM, 256 GB SSD), coming from an early 2008 MBP 15" it really feels great, everything is incredible fast, almost instantaneous, but... I'm experiencing two VERY annoying problems with OSX Mavericks:
1) 2/3 times a week the whole system freezes up and I need to reboot
2) once a week the sound output stops working and I need to reboot
Googling around it seems I'm not the only one experiencing these issues, too bad I can't go back to OSX Leopard.
Regarding OSX Terminal, I'm an heavy user since Leopard but it's a shame that after upgrading to Mountain Lion (an now Mavericks) I discovered that they broke VIM vertical selection since control-shift does not generate a keycode anymore [1].
Anyone with the same problem? I tried iTerm recently and I don't like it! :-(
