ELI5: Why buy an expensive computer monitor if a HDTV of the same size is cheaper and has the same resolution?

a 1080p 32" computer monitor can cost 500 dollars, but a 1080p tv thats 32" can be bought for 150. Is a computer monitor better, even though the resolution is the same? The picture quality is also pretty impressive on some of the HDTVs, would you really notice a difference?

Monitors have better response times, more accurate colours and some even have features like USB hubs. 

TV's don't have fast response times and therefore have a lot of input lag, which is fine for movies and such, but for applications and games, monitors are better. TV's process the image to try and make it look as good as possible, but it doesn't mean the colours are accurate, which is important for things like photo and video editing. This processing takes time, so a TV can have a response time of anywhere from 10 to 60 milliseconds, but a monitor usually has response times or less than 5ms, often 2 or even 1ms.
