X200t is just too convertible-y for you, and the standard X200 just doesn't last long enough for your 18-hour plane rides, the X200s won't do you any good either. If you only need 10-hours of juice, however, this unit is just about perfect. The ultraportable does give up some raw horsepower in order to deliver such stunning life, but true road warriors will certainly make the sacrifice. Critics over at Laptop Mag were duly impressed with just about everything the pricey X200s was packing, noting that the keyboard was "excellent," the design was sturdy and the screen was clean and crisp. Additionally, they found that the power decrease wasn't too noticeable in real-world use, though they did lament the omission of a WWAN module (agreed!) and webcam. Bottom line? These folks found it well "worth the splurge," though we'd recommend giving the full spill a read if you're seriously on the fence.
