I have both the GN 10.1 and the 8.0. I prefer the 10.1 to do most of my work on. I use it to draw and it has more memory (32gb), not to mention the extra room on the screen is great for my drawing needs. The 8.0 is a great tablet for traveling with and using on the go. I use it for appt.'s and when on the go, as the screen is bigger than my GS lll and easier to hold than my larger 10.1. They both are great tablets, but for my main tablet I use the 10.1. The 8.0 is used for mostly some games, taking notes, and reading.
Also want to add, that you can open in Cascade view more apps on the 10.1 and move them around the screen, whereas on the 8.0 you only have the choice of having them side by side, so only two apps open at a time. I think you have to know what you are going to use it for and what size, amount of memory you need on board, and stuff like that to make a better choice.
