thanks everyone for encouragement.
i did get a bit worried, but...
i have now opened it !
and even started using it, a little bit. but am typing this on good ole windows 7 laptop, because something went wrong when i tried to access GN on the new chromebook.
i have not yet been able to link it to my internet wi-fi, so was using guest mode.
when i tried to access GN it thought i was anew user, and somehow i must have made a mistake.
as chrome is linked to google, and i had entered my gmail to get started on chrome, it automatically entered that to GN.
but i am joined to GN on another email, not gmail.
now i am stuck. i hardly ever had to put login details on here, i just kept it open. also i had passwords saved to this machine.
yet now i cannot find those for GN in settings. other ones appear, but not GN. i wonder if i hve over-ridden it somehow.
this is the kind of thing that worries me.
also the keyboard is hard to see, tiny lower case letters on grey, whereas this has bold big capitals on black.
also i find watching videos on chromebook, i have to angle the screen almost shut, and look up under it to see people's faces properly. i guess you will laugh at these quibbles.
i would have preferred to keep this machine and have it updated, but i do appreciate the great gift.
the person who gave it to me did not know that the word chromebook related to computers, so when i was thanking her we were at cross purposes. so you see she could not help me with it.
