Well of course the Surface Pro isn't a laptop. Just like the iPad isn't a laptop. The form factor of both devices just doesn't make it a competitor to a laptop.

However, the Surface Pro is the only tablet that can do everything you can do on your laptop. That's the important distinction. It just can't do it well (form factor again).

I've personally found that the Surface Pro is great to bring to class and with an external monitor/keyboard/mouse, it makes a great daily computing device. However, I am thinking about buying a ThinkPad Yoga to replace both my Surface and Laptop. I need something where I can take notes (going paperless rocks), but also something I can write code on.
