Microsoft's Surface Book is now available for order in the UK with prices starting at £1,299 and climbing as high as £2,249.
The £1,299 model comes with 128GB of storage, 8GB of RAM and an Intel Core i5 chip, while the £2,249 model has 512MB of storage, 16GB of RAM and Intel's top-end Core i7 processor.
Two mid-range models are also available, from £1,599 and £1,799 with different storage, RAM and processor options.
Most potential buyers are unlikely to be too miffed at finding that the most expensive model is showing as unavailable at present, but all other models are still on sale.
The Microsoft Surface Book can also be picked up from retailers including Currys/PC World, John Lewis, Selfridges, Harrods, Amazon and Very.co.uk.
The Surface Book was announced in October and is Microsoft's first own-brand laptop. The company claimed that the device "redefines" what should be expected of a laptop with a 13.5in 3,000x2,000 screen, included Surface Pen and a redesigned hinge.
It's also the "most powerful" laptop yet, according to Microsoft. The Surface Book has a second Nvidia GeForce GPU in the keyboard component which the firm claimed makes it ideal for photo and video editing or for rendering 3D models and schematics. This keyboard is removable, and the tablet component switches to the integrated GPU when the screen is detached.
Not one to be modest, Microsoft said that the laptop's Intel chip makes the device 50 percent faster than the MacBook Air and better performing in terms of battery life.
The Surface Book comes with a premium MacBook-style metal design and glass trackpad, and features Windows 10 Pro, 8MP and 5MP cameras, a full-sized SD card reader, a mini DisplayPort and up to 1TB of flash storage.
