I might have to replace my current monitor in the future. I see there are pretty good prices on the curved screen. 

Can it be mounted on a VESA stand.

What are some of the cons I need to be aware of.

Does anyone here use a curved screen, if so what size and would your recommend it to someone that have poor eye sight.

My current monitor is 23 inches. It is a very old Sceptre  LCD and has served me well.
