Agree. I see user's eyes glaze over with each command line option, and 
we have added aliases to embed some of the details as well as having 
sensible defaults.

I often use perf-list to lookup an exact event name, and I do not want 
to see it taking many seconds to minutes to run (not everyone is running 
on an SSD). I also run perf on many different OS versions with an NFS 
home directory, and do not want to see a cache explosion (I have buildid 
disabled for this reason).
