The same might happen with any add on box, (it may even be more likely). I wouldn't pay a large premium for built in Internet services (I don't want smart just connected with Netflix, DLNA, iPlayer) but I would throw the TV away if they stopped working either.
4 year old Sony TVs have internet services that still work fine, I like not turning on the PS3 with fan noise and power consumption, I like not buying an extra box and needing to manage an extra remote and interface. I record TV on a MythTV box and I like watching it over DLNA using the TV's decoder and scaler which are better than those provided out of the box by MythFrontend. Yes it may fail at some time in the future but for the $13 or so added to the BOM (for Wifi which I don't actually use) it is a definite win for me even if it stops working tomorrow and I need to get an extra box or rely on the PS3.
