Oh I remember you. You were able to get another iPod I suppose.
Well...if Apple gave those standard, there wouldn't be too much money there. It's the same reason they took away wall chargers from an iPod package. Money. I believe the headphones are supposed to come out this fall, but I don't remember exactly. The battery life is supposed to be improved, but with the way I use mine, it seems to drain rather quickly.
EDIT: Do you really need the screen to be that bright? Tone it down a little. Believe me, you get used to it, and its easier on your eyes. WiFi should be fine to keep on. When you put your iPod on standby, WiFi turns off in a certain time period, and will reconnect when you take it out of standby.
