I'd say my experience is probably the norm
Yes, but as passengers we can only judge (and make our purchasing decisions) on what we experience.
I've been one (inbound) and thought the terminal was a disappointment.
If ZRH has an indicator to tell you the platform for the next shuttle,why can't T5 have one? I (amongst about 50 others) had to rush from one platform to the other to avoid missing the shuttle - completely ridiculous and avoidable.
Once landside, it was difficult to find anyone to get information, the signage wasn't great and I thought that the area after clearing customs was pretty small for the size of the terminal.
What was a major improvement was the handling of busses - top marks for that.
All in all, it's not bad, but given it is an April 2008 launch, I did expect better.
