These days it's upper middle for the U.S. I would say. For example the new top-of-the-line Dell consumer laptop, the XPS 13, starts at under $1000 (900€). When I got an XPS nearly a decade ago, it was a model they had at a considerable discount (as I recall it was an overstock situation or something) and it still cost me $1350.

As far as I can tell, low-end, mid-end, and high-end laptops are not only more powerful than the laptops of 10 years ago, they're also considerably cheaper at each level. I can't say for ultra-high-end laptops, I'm sure you still can spend $2500 on a laptop if you want, but even the MacBook Pro starts at only $1300 these days.
