i am a little new to the internet tablets, and i am getting a n800 for xmas. my question is: since the release of OS2008 is a beta, should i still complete the upgrade or should i wait until it's official?

and if i go foward with the upgrade will i be able to update it eventually to a stable version or will i have to flash it again?

and final, when i flash, will i need to reload all the apps i had installed from before?

thanks.
