The upgrade certs aren't completely useless. A lot of it depends on where you live and when you try to use them. It's easier to use them on weekends than during peak business travel times (fewer elites) and it's easier to use them at certain airports (like MCI). Again, it's fewer elites to compete against. I managed to use 4 of mine before making silver out of about 12 or so upgradeable attempts.
To be fair, this was pre-EUA. I could beat out lazy elites before and you won't have that opportunity. Perhaps weekends are now your only practical chance.
