Media Center: Proven that I need all 3 (PS3, XBox360 and NetBook)

I have 3 devices that take the role of  media center.  There were times when I thought it was kind of overkilling, but the experience I had in the last several days taught me that I need to keep all 3 of them.

• XBox 360 is the ONLY device that allows me to both watch and manage HDTV recorder by the machine in the closet.
• PS3 is the only device that can play Bluray disc in my home.
• NetBook with XBMC is the only device that can play pretty much ALL the files without hicup.  XBox360 and PS3, on the other hand, gives me strange results when playing mkv and other formats.

The O!Player is the one that I kind of regret getting now that I look back, which explains why I haven't turned it on for months.
