So someone else's pretentiousness influences your decisions? Strange.
I also use an iPad, but my comment will actually be tablet related in general, so therefore, relevant. I find that when I brew at home, its more of a hassle to remember where I placed it, keep it out of the way, etc, so I end up just using my computer like always.
Whatever tablet you get, I recommend using a program that is sync-able with a full version on your computer. Tablets are fun, and have some great uses, but when I'm making recipes, managing ingredients, etc, I like to be at my full-sized laptop with a keyboard.
