You do not have wifi Which saves one more high-bandwidth device disrupting your network and polluting your house.
One big downside: streaming services are all in 30fps and 24fps not.
More Over Amazon Instant Video is not 5.1 surround stereo but only. But that's all Sony Bluray player.
The winner is Samsung's BD-F7500 Which has 24fps streaming output and perfect Amazon Instant Video. On the otherhand, the BD-F7500 is therefore twice as expensive and does not offer the same quality of DVD scaling as the Sony BDP-S4100 (I'm using component out from an old Panasonic DMP BDT100 so I'm not using the Samsung's DVD scaling).
