That's right; it's a Thinkpad X200s. Avoiding a reflective screen should go without saying, but it's surprising how many people don't understand this. The X200s is definitely the best I've ever used for mobile purposes: 1.2kg, high-res matte display, battery is easily swappable. It's got a low-voltage chipset, so with an SSD you can get six hours or so from a 9-cell battery, though usually I won't spend more than half the day outside since the seating is usually not as comfy. I do use it in the sun occasionally for short periods, but a) I live in Seattle, and b) it actually gets uncomfortably hot if left in the sun for too long since it's black.
