Yes, I bought one on Sep 1st :-)
It looks much more decent than the "fat" PS3 with its glossy surface.
Setup was super easy and it works easy. You can customize the interface with themes and your own backgrounds.
Noise level is a low frequency from fan and BD drive. It's okay like a small PC or s.th. comparable.
The Eject- and Power-Buttons are backlit. Looks very good and it should look like this on the Beosound 5, too ;-)
Copied my holiday photos to the PS3 and it can even rip your CDs into different formats (AAC, MP3 ...).
Navigation on the PS3 with its XMB menu is absolutely simple. Perhaps it's more fun while watching DVDs, Blurays etc. when you use the original remote instead of the controller.
When somebody converts the Pronto files of the Logitech Harmony PS3 adapter, we should be able to control the PS3 with the Beo 5 remote :-)
Thought of buying a multimedia player, too but after getting the PS3 I cancelled that idea. The PS3 suits all my needs as it can access clients inside your networks, too.
With the optional PlayTV you get a dual DVB-T tuner that can record films, TV-shows etc. directly to the PS3 while you're watching another program etc.
Timeshift works, too. PlayTV was sold out here in my region, so I have to wait a few days, to get it!
It was a good choice for me to buy the PS3 and modern games are more than amazing :-)
