Plasma computer, Plasma TV Video

Would a high end Plasma TV, like a Panasonic 42" Viera TH-42PZ85U, make a good PC monitor?

I would have to connect it using a DVI to HDMI converter cable or I could connect it using a VGA cable. The Panasonic comes with a VGA connection.

Using a Plasma TV would I be able to play games, do office work and all of the normal things people do with a regular LCD monitor? Would it be blurry, have ghost effects, and or lag?
