Hi everyone..
I've already update my Ipod Touch 8gb 2nd Gen to iOS4 with iTunes 9.2. Here is my summary of this new OS for 2nd Gen Ipod Touch:

Advantage:
1. Can create folder (combine apps into 1 folder)
2. Got iBooks application (but need to install the app from Apps Store for free & many book are free thru Apps Store.)
3. Can create a playlist of your favourite music.
4. Got new wallpaper that come with iOS4.
5. Airplane mode in Settings.
6. All email inbox can be combine into one.
7. Push notification seem to be faster than before.
Disadvantage:
1. No multitasking for Ipod Touch 2nd Gen. 
2. No Homescreen wallpaper for Ipod 2nd Gen.
3. Drain out battery a bit faster than previous iOS.

0.7 MP

lol the camera is a added bonus, no one ask you use it for photography.

yes, you can change itunes in diffrent pc of course 

i think you just need authorize your account in your pc only... max is 5 account.

yes, you need authorize account only.

maybe... i know apps can transfer as long as you have either 1 copy on either side (ipod to pc / pc to ipod)...anyway everytime you purchase apps, apple got record one, so you can re-download it if you accident delete apps... of course,again, authorize your account in that itunes.

about music and picture i m not sure about that, you can untick it to prevent lose it...or copy whole song you synced to the new pc.then redirect the song again 
not sure about that.
