I just noticed the anything black trails a bit, you can really see it if you enable flash then check out this site:No problem. What do you mean ghosting? The widgets have a ghosting effect when you drag them but I'v not witnessed any other ghosting due to the screen.

you can see it trailing, it must be to do with the LCD refresh rate. it's the only thing that bugging me really, the rest of the unit is really good. Shame they didn't put an IPS panel in it though.
