Pros: Nice drive, quick and quiet

Cons: Note that older SATA chipsets will not recognize the drive unless you hard-set the drive to SATA 150 via jumper. The OEM package lacks a jumper so you have to supply your own

Pros: Very easy to set up, intuitive XMB menu, loads Blu-ray quickly and plays AVCHD discs

Cons: Sony's DLNA implementation is very limited, more so even than that PS3. While it will play .mp3 and photos from my MediaSmart server, it refuses to recognize any video files at all.

Overall Review: Bottom line, if you need a Blu-ray player, it does a fine job, but if you are looking for a network media streamer look elsewhere

Pros: Well made unit, solid web streaming of video and audio. Excellent color picture when lighting conditions are good.

Cons: Auto configure DDNS setup fails without explanation (likely due to the existence of another web server on port 80), leaving manual static IP setup as the only option if you want to use the Panasonic viewnetcam.com DDNS service. Picture washes out to grainy black and white in low light and the "night view" option is worthless.

Pros: Easy setup, small form factor, quiet

Cons: No uPnP media server, and no option to install one or other apps with stock firmware

Overall Review: Indications in other reviews are that this unit is the same as the NAS 4220, but has anyone attempted to install the Raidsonic 4420 firmware that supports Twonkymedia as an add-on?
