Thank you for posting some fantastic information. I might look into some of the third party apps, but I'll probably be fine running the machine like I should. Really, I don't use it for more than the most basic tasks (web, email, music, videos, IM) so I'm not too worried.
One question: as I mentioned, I have the 160GB HD. There's 118 GB available. Considering that I'd like to buy Parallels and install my old version of Windows on the machine (or Visa, if I so choose), I know I'll be adding to the HD space.
So, the big conundrum I have is how much HD space to keep open? I have 60+GB of music that I kept on an external HD when I used a PC, but now that I have the space, I kinda want to put that on the regular computer so that I don't have to be connected to the HD to listen to the music.
Will THIS slow down the computer? Or can I throw the 60-80GB of multimedia on there and let it keep speeding along? Will adding and removing data eventually slow this beast down?
Or is it, as you say, unflappable.
