Did not plan on getting both , ordered the 11 I could not cancel in time , fedex signed for me , causing me to have to activate before sending back to xfinity mobile .I ordered the 12.9 a couple days after ordering the 11. Was going to not sign for the 12.9 and just keep the 11.Well fedex once again signed for the package so I had to activate the 12.9 ,so here I am with booth and after a couple of days I just decided to keep both .The 11 is my media throw around tablet, and the 12.9 has become my computer thats not a computer. I am learning a lot about this new os , one trick I have found out is that on the multi app bar is that if you put multiple apps in a file box then drag it to the multi apps you can open that file and drag all apps in it to multi pane .Making it possible to have more apps avaliable in the bar . Hope this helps. And in the future don't ever question the wabber Jacky you have been warned .?
