Your question seems to have been largely answered but, since you mentioned my name in the title of your post, I'll chuck in my tuppence worth anyway:
The laptop (as described in TTT's first link) has a solid state drive (SSD). That usually adds quite a bit to the cost when compared to laptops with conventional hard drives. Further, it's quite a large SSD, which pushes the cost up even higher.
It's got a fast (i5) processor, meaning that it'll cost more than the slower (i3) version. Further, it's '10th generation', which means it's the latest, all-singing, all-dancing version. (The processor speed, of 4.2 GHz, is way above the speed found in most laptops, which typically have a processor speed of 2-and-a-bit GHz. It's even considerably higher than the processor speed in many gaming PCs).
It's got 8 GB of RAM which, while not massive, is more than cheaper laptops have. (Up until recently, 2 GB might have been seen as the norm for budget models but 4 GB is becoming more common).
It's got 'little extras', such as a fingerprint reader.
It's built for heavy-duty use, with a metal case.
The best quality laptops do tend to be expensive to buy new but they don't hold their value, meaning that there are some excellent second hand bargains available. The laptop I'm typing this on cost around £1200 when it was new (about 4 years ago) but I bought it for just £199 last week:

It's superb. There's not a mark on it and, apart from the absence of the original packaging, it would be impossible to tell it from new. It really feels like I'm typing on a grand's worth of computer!
