By critical reviews of the "limited" flash memory of 12GB, I started to research what games I then possibly still would be able to play.
Since the Amazon info indicating to the games almost always the used disk space with, I quickly found out:
I can do a whole lot of games spielen.Inzwischen I WipeoutHD downloaded and installed from the store for 7,99 and games also parallel Killzone3, Uncharted3 & Dead Space. And I still have 7.1 GB free disk space. As far as I am glad for the reviews that complained about the lack of memory, because I was informed by them beforehand and said: For me, the memory is more than sufficient.
Also recognizes the PS3 my PLEX server in the home network and streaming movies easily - even a thumbnail of cover provides the PS3 - this is an unexpected added value for me. All media will be played - even FullHD MKVs. Although me an acquaintance said that MKVs not be played by the PS3. Per PLEX any case it works.
Chance I read of a high-pitched tinnitus or very loud Blu-Ray drives, and was worried that this was a general problem of PS3. My son the 500GB variant has ordered and my give neither his PS3 still a tone of itself. Thus, I say simply that loud noises do not affect all PS3 and can only recommend to exchange such noisemakers at Amazon for defect. The Blu-Ray drives in both our PS3s are indeed heard - but when a movie or game is running can no longer hear.
Also lack of build quality, I can not confirm - the drive lid slides when pressure is applied to "Eject" and then closed manually. That does not do now, however, 50 times in a row, but in film or game changing. I'm sure the PS3 is so easily during their "lifetime" survive.
In VOD, or media playback without Blu-Ray use the way you hear nothing. Also, the fan does not bother me in the least.
I run the PS3 on a 3D projector and the sound comes from all corners by 5.1 and can only say: WOW! - A visual and acoustic feast for the senses. Never before was so much fun I gamble. Originally I wanted to use only yes LOVEFiLM and max cathedrals, but now I play whenever possible and fly in 3D with 5 meters screen size a wipeout slider or walk in the 3D depth of Helghan. Just great!
My conclusion and tips for 170 I did everything right and look forward to every PS3 session.
Update on 08.01.2012 - now I'm playing in parallel: Uncharted3, Killzone2, Killzone3, resistance2, Dead Space, The Darkness2 and Just Cause2 + WipeOutHD. I still have 6.5 GB free.
