I'm really interested in including a lot of the tips here in my upcoming, and future, rebuild(s). However, I am a relative newbie to things such as symlinks. Are they really worth it and are there any cool references or further tips you can provide on their application? My current plan is to just recover the preferences from a time machine backup after upgrading to SSD as my boot drive in my early 2011 MBP and then moving the existing HDD to the optibay as a data drive for media, etc. I really can't decide whether this is too much effort for the number of times I am likely to rebuild in the near future...
I also keep a running list in notes for terminal commands such as 2D dock and delay settings. I find most of the default transitions way too slow, but turning them off completely is jarring and disorienting. "defaults write com.apple.dock expose-animation-duration -float 0.075; killall Dock" and "defaults write com.apple.dock workspaces-edge-delay -float 0.1; killall Dock" go a long way to making things feel snappy.
As far as symlinking goes, you might consider Stow a useful tool to set up the links ( http://onethingwell.org/pos... ), although then again, if you only do this rarely, perhaps not.
On my MacBook Air, used on train commutes, no tweak has increased my productivity like this one: http://www.ewal.net/2012/09...
