I've enjoyed my LTE Surface Pro, but my Surface 3 is still on the shelf. I had bought my wife a Surface 3 as well when I saw a good liquidator deal and she has turned me down on upgrading to a Pro. We'll be looking at the GO LTE for her in the fall. I installed the Memu Android virtualization on my machine reskinning it with a Nova Launcher and it works quite well for my Kindle and NY Times apps.
I agree that the Atom on the Surface 3 works better than expected.
