Cons
Con Less consistency across brands
As mirrorless cameras are relatively new, differences in capabilities and how they handle between various brands are much larger than those of DSLRs.
Con EVF introduces a delay over OVF
Con Can't change the lens
You are stuck with whatever comes with the camera.
Con Less manual control
Con Image quality ceiling is below that of other types of enthusiast cameras
Within a price range of about $1000 USD best point and shoot cameras can sometimes come close to DSLRs and mirrorless cameras in terms of image quality, but they don't offer anything comparable beyond that price point.
Con Some P&S cameras lack a viewfinder making them difficult to use in bright light
A good number of P&S cameras forgo a viewfinder altogether so the only way to compose a shot is by using the LCD monitor on the back of the camera which can be difficult to use in bright light.
