Doesn't plasma screens have this flaw called 'Burn In'?

For example; you leave the game paused for an extended period of time then when continuing it back again there are some parts of the game image that is burned onto the screen.

Another example would be the Astro logo or cable channel logos (i.e: HBO, CNN, ESPN) it remains on that certain upper right hand spot for some period of time and the image is 'burned' into the plasma screen.

If I were to opt for a screen for my gaming rig, I'm going for the LCD screens as it doesn't have 'burn in'.
