I bought the 21.5" model and have used it for 2 weeks - so far it has been fine.

--Pros--

> Has both DVI and VGA - DVI is higher quality than VGA but it offers compatibility for both
(NOTE: DVI cable not supplied! I recommend buying a DVI-D cable separately)

> Very light and thin - looks great and is very easy to move

> Tilt function - useful for moving monitor to perfect angle
(NOTE: the way it tilts is not obvious - you must hold the bottom and the top in different hands, and gently push back with the top hand)

> Touch buttons with on-screen menu - easy to use and to change options quickly
(NOTE: includes the ability to change to different preset settings)

> 5ms response time - great for gaming (and watching movies)

--Cons--

> Although panel is of v. high quality, there is slight grid-like pattern of the pixels towards the bottom of the screen when viewed from some angles

> When viewed from sharp sideways angle, corners of the monitor have a bluish tinge - this is normal for most monitors, but don't be fooled by Samsung's claim that this does not happen

------

Overall this monitor is very good and I highly recommend it. Better monitors are available, but for this price, it is one of the better monitors, especially given its size and resolution
