On the OSX side, if you use Alfred[1] then you already have a clipboard manager[2]. I have cmd-shift-v set to popup Alfred's clipboard history. The nice part about Alfred is you can search (text and regex) your history and use cmd+1-9 to quick select the first 9 in your history. You can also exclude certain apps from being save (ie password managers) and save frequently used things to snippets (I use this to save frequent responses to customer tickets)
The number of times this has saved my ass or at least significant amounts of my time is fairly large.
