I'm struggling trying to judge the strengths and weaknesses of the two software environments. Help would be appreciated.

It appears that the hp zd7180 has a separate box for the TV tuner. Is this observation correct? If so, does the Sony GRT 390 have a similar box?

Does Sony GigaPocket have any unique advantages over Mictosoft Media Center?

Is Sony XBRITE the same as hp BrightView?

Does the hp 17" screen have advantages over the Sony 16" screen? Do these screens handle HDTV 16:9 aspect ratio?
