Pros
Pro Optional keyboard accessory
The keyboard ($130) doubles as a screen protector when not in use, and magnetically attaches to the bottom of the Surface. It's thin, so key travel is shallow, but it's a very capable keyboard. It features 5 levels of backlight, as well as a (rather small, but very high quality) trackpad. It connects directly to the Surface, so there'd no need to charge the keyboard and you don't need to worry about bluetooth.
Pro Kickstand
The Surface 3 has a kickstand on the back of the tablet so that it can hold itself upright. It has 3 positions - one upright (almost vertical), one at almost a 45 degree angle, and one fairly close to flat (this one is useful for drawing or typing if you don't have the keyboard).
Pro Optional Pen accessory
The Surface 3 (when coupled with the $50 pen) can register 256 levels of pressure sensitivity, and also has Palm Block technology. It makes for a good experience when drawing diagrams, sketching or even just doodling. Clicking the button on top of the pen opens OneNote - Microsoft's note taking application.
Pro Portable
At just 267x187x8.7mm (10.5x7.4x3.4") and weighing 622g (1.37lbs), this is a portable machine. Some other tablets are a bit thinner and lighter, but the kickstand really helps you comfortably use it anywhere (you could set it up in the kitchen for a recipe instead of laying it down flat, or rest it on your chest while laying down in bed instead of holding it up).
Cons
Con Fragile
The screen is very susceptible to being damaged. Here's where its generally beneficial light weight can be a downside. It requires as much protection/care as a tablet does -- it is not as sturdy as a laptop. The back cover will scratch fairly easily if dragged along a table as well.
