well, first off, if you don't know what it means to root your phone, then you ABSOLUTLY SHOULD not be attempting it. Rooting your phone disables ability to get pushed updates, and should only be done by the most power user who wants complete control of every deep level of their android OS. Also, just some info about this...the n1 has plenty of internal space, i have 40+apps installed and still have plenty of room. the reason google does this is if you think about it, a good solution to a difficut problem. if google allowed you to install all your apps on a non-protected sdcard, u could simply swap paid-for apps and the developers would have a HUGE problem with that. the way a platform attracts developers is by helping them make $$$. if it were so easy to steal apps, no one would develop any for the android platform, and without developers and apps, the android platform would fail. this is the tightrope walk that has to be done between wide open and opensource, and then locked down paid-for apps. google is currently looking for ways to lock down portions of the sd card to allow installs there, but this is a total NON-issue on the n1 because it has so much space for apps. most apps are very tiny, and use the sd card for the bigger media files and other stuff the app uses. Really, unless you run out of internal space on your n1(which u wont) don't gt causght up on the number-size allocated to internal storage.
