AffirmBrest, I agree wit ya. Proceeding to your destination would be a safe thing to do, since your seperation is already correct at the time you lose comm. In a short while, ATC will determine that they've lost contact with you (comm) and will notify the destination airport and everything can be done without rushing.
Besides, if you're VMC at FL350, the airports down below might not be. If you continue, you have your ETA, EAT and stuff so they know where you're gonna show up at what time. If you're just gonna wander on down there at your own discretion, that would be dangerous in congested airspace.
But seriously, in modern airliners, the chance of getting a comm failure with all the comm radios in there is very unlikely.
