For someone who is using Photoshop as a professional, $999 really is not far off from entry-level. People easily spend $2500+ on computers for professional work that requires high performance. Sure you can use a $350 Dell Inspiron for Photoshop work, but it's not going to be very practical. Performance, battery life, and even the actual screen will be pretty poor at that price point.

though, Photoshop professional work is not entry level.

My uncle is a woodworker, his tools are not entry level.

He doesn't buy the best of the best the market can offer, far from it, but his tools are not entry level.

they can be considered entry level only if you compare them with the state of the art in his field of work.

Entry level of the high end segment maybe.
