I researched TV's for ages as we were still stuck in the world of CRT!
It came down to this one versus Pana Viera. Originally I wasn't sure about the main draw to LED vs LCD but a trip to a local reseller confirmed that Sony's LED technology is truly very good. The Pana units are very close but we already had Sony blu ray players so that swung it. Some LED screens do seem to be a bit too bright but that may be the way they are left running in the shops and maybe not configured as well as they could be.
We use the network functionality a lot (wired Cat6) so can not comment on wireless capabilities and dongles etc. The TV is also 3D capable but we aren't interested in that as yet. Image quality from blu ray and HD is superb and that is what it's all about for us. SD images are also excellent and there's a whole host of ports for connectivity until your heart's content.
Sound is predictably tinny as the chassis is so thin there is no way any decent amp/speaker tech could be crammed in there. Instead we have used a Panasonic sound bar and woofer that sits discretely behind and it is brilliant for under £200. Excellent differentiation between high,mid range and thumping bass (if you turn it up).
Sony S380 blu ray and Humax HDR500 (freesat) recorder completes the setup and, for very sensible money, this is a very good entertainment platform. My work involves integration projects at many high worth homes and I can safely say that this setup gives vastly more expensive installations a good run.
Hope this helps.
