So I love the Surface Pro. It is awesome. But I lust the Taichi, and when I finally got my hands on one, I was fortunate to be able to exchange the Surface Pro for it at the Microsoft Store. I have to say, if you can get to a Microsoft Store, they are awesome - the customer service there is exceptional. Anyway, my reasons are thus: Each of these devices is a hybrid. The Surface is a better tablet. The Taichi is a better laptop. I will be using the device more as a laptop than as a tablet, so I figure I'd get the form factor that suits my needs better. I racked my brain for about a day trying to figure out whether or not I should make the switch and this Pro / Con list is what I came up with: Surface Pro: Pros: Smaller, better build quality, lighter, better stylus technology, cost, made by microsoft so support will be top shelf Cons: Thicker(?!), not as flexible form factor Taichi: Pros: Two USB 3.0 ports, two video out ports, backlit keyboard, crazy presentation mode, matte screen for laptop mode, sexy cover included Cons: Bigger, heavier, kinda stabby in tablet mode, no touchscreen in laptop mode (hate this) So each device has a lot going for it and neither is perfect. I came down on the Taichi's side because I find that the things that are good about it are things that I will actually appreciate more. Good times!
