The process of making a com ready to retire is always like a time trip to the past as you browse through all the files and it was like "oh man! These stuff is like from another life time..." when it was actually just 4 years ago. But then year 2006 definitely sounds like another age now.
You also get to realise a lot of stuff which you thought were important is actually junk in the long run, but ironically a lot of other stuff which you might have thought to be junk are now cherished memories.
