Thank you for contacting Samsung Customer Care.
The N8000 is a 3G variant of the Galaxy Note Tab, you are able to make phone calls and browse the internet using a network provider of your choice. Please be aware that there are two major different models with the Galaxy Note Tab, there is the GT-N8000 which works on the 900 band, this means that Optus and Vodafone will work and network providers under them, and there is the GT-N8000T which works on the 850 band, this means that Telstra and the network providers under them will work.
The N8010 is a WiFi only tablet. This tablet is unable to make phone calls unlike its 3G variant.
The N8013 is an overseas model of the WiFi variant and has not been released in Australia.
I hope this has been some help to you.

and from a fellow member:
"A friend of mine got his galaxy note 10.1 from states before it was available in Canada. He has a 16 GB model and it is N8013. I got mine two months later in Canada and it is a 32GB model N8010. (haven't seen 16 GB variants yet)
I did a comparison between the two. The obvious differences are: updates are available at least a month sooner for the N8013 models before they are available for the N8010 ones, out of the box N8013 came with some apps like Kno textbooks that were not found on N8010 model out of the box, the screens on N8013 model has a much better color saturation and produces deeper colors than N8010 model, and finally the N8013 models weigh noticeably more than N8010 models which can be a result of the materials used in making the two. N8013 has a much better built quality than N8010 models.
Hope this helps"
so i guess i got lucky! WOOT WOOT!
