TVs don't display things the same way a monitor would, at least not by default. They overscan, meaning they cut off the edges of the picture. (It's a TV thing....long story, google it). This means the sides of your desktop get cut off. The TV might have a mode to disable overscan (often called 1:1 pixel ratio) and there are tools to correct for it in your video cards output, so it is definitely something that can be gotten around, but you should know what you are getting into. Read the manual for the TV first.
The other thing is how far you will be sitting for reading text and such on this monitor. 1920x1080 is the res normally used for 23-25" in displays, not 32. It's going to display things kind of big and fuzzy compared to the way a monitor would, since it is meant for displaying video. This may not be as big of a deal if you have a normal display for text and such, depends on what you are doing with it.
I know several people happily using HDTVs as monitors, but it's not for everyone nor does it work well with every TV. Research, research, research. (Googling "sony kdl-32ex503 computer monitor" or something like that might be a good start)
