Microsoft talked about the Surface Book having up to a 1TB solid-state drive when it announced the laptop/tablet hybrid, but you couldn't actually buy it on launch -- 512GB was as good as it got. Well, that extra-capacious model is now available for pre-order... and to no one's surprise, it won't come cheap. This ultimate configuration (which also includes a Core i7, 16GB of RAM and dedicated graphics) will cost you an eye-watering $3,199, which makes the $2,699 512GB model suddenly seem like a bargain. Not that there's a rush to buy the 1TB version right away. This and most other Surface Book models won't ship for another 7 to 8 weeks thanks to brisk demand, so you might as well think it over before you drain your bank account.
