I have a Sony Blu-ray (view at amazon.com), a Wii and the Xbox that can all get netflix and other services. The Sony is pretty cool and I use it pretty often. However, I primarily use an Acer AspireRevo (view at amazon.com) with a cool Lenovo Multimedia Remote (view at amazon.com) to push Netflix, Amazon, Pandora, Hulu, Podcasts and other online content to our 42″ Toshiba TV (view at amazon.com). The revo even has an HDMI out.
I use wifi to stream my online content and have been typically very happy, but I’m sure if I bothered to run a CAT5 it would be even better. Oh and I shouldn’t forget to mention that my Tivo Series II(s) can also connect to many of these online services but they are way too tedious.
