Made a purchase last night...

So last night I took my wife hunting for a laptop. Previously she had the Surface Pro 2 and didn't feel right with it and so she had returned it. Now we stumbled on to the Thinkpad Yoga (stylus) at Microsoft store. For $1099 I really liked the unit. She wasn't so crazy about it mainly because of the screen size and stylus had no eraser feature (yes the surface pro stylus eraser works on it). We then moved on to the Idea Pad Yoga Ultra book 2 in 1 11.6" for $799 with 128 SSD and 4GB ram etc... She wasn't crazy about it. I took her to look at the Surface Pro 2 again and for some reason she was into it. She got the Surface Pro 2 (128 Gb) with the type cover and paid $1,200+change. I don't get what happened, and Im not sure, because of the larger screen, that the Thinkpad Yoga wasn't a better option for her. I have the Surface Pro1 and I really like it, but I just have mixed feeling about the whole thing.

Any thoughts?
