Game improvement ideas for computer with no internet connection?

[bonanz]

I'm looking for clever ideas on using a computer that has no internet connection as a tool to improve your game. For the sake of discussion let's say you cannot install any AI programs like turboTH or poki.

So far I have things like digging through archives and saving a ton of good posts to a word document to read through.

saving a bunch of hand histories to review sessions of my own to make notes on and analyze.

things like that... any other ideas would be appreciated
