True. Word barely is quite subjective, but what I would first do is to speed read this:

By speed reading I mean just read really those that look relevant. Might be hard to spot but it's good skill to learn. Bit like doing research for your thesis or something like that.

And more stuff from here:

And just general note:
- If you feel like you are typing commands to xterm like monkey and not really understanding what you are doing then stop. You are not ready do some more research and think.

I haven't overclocked my n900. Maybe after year or so when i have seen enough results in here.
