got the 42W653 recently, i think its the same model as above but renamed for different countries.
anyway, i just wanted a solid gaming set without 3D that had
minimal input lag. this is the midrange in sony's 2013 line but seemed to fit the bill and offered some nice features like usb recording and built in wifi (no dongle) as well as the usual playing files from usb, picture in picture or picture by picture, and dlna support. sony's top 2013 models (non 4k) come with a triluminos panel, local dimming, nfc, active 3D, and an extra 600hz of motionflow etc but i didnt need most of that.
design is very slick overall, everything from the tiny bezel to the stand (also acts as a wall mount so need to buy extra shit). its really light too if you want practice your deadlift?! the sony logo acts as ir receiver for the remote and lights up... ui wise its pretty simple (not the XMB thankfully), i prefer this to samsung's compacted interface.
pressing the SEN button brings up a list of all the on demand services, it supports most of the major video services and also has social media (facebook, twitter) and skype (webcam accessory required). browsing youtube on TVs has come a long way since i last checked, typing still sucks with a remote but it suggests what letter you might want next which saves a lot of time. bravia sync tech comes with most sony stuff and allows you to control devices with the TV remote, you can run through the XMB on a PS3, control certain audio systems etc - if you have a lot of sony devices it might be nice.
i'd say its a good all rounder for sure at a reasonable price.
here is a thread over at av discussing this particular range
