This is true if the DB is properly designed, however most of the 
conversions i've ran from myisam to innodb dramatically and harshly 
affect performance until things get fixed. The main reasons are "Select 
*" statements in the code, lack of constraints and views, and probably 
the biggest cause is allowing null in the column definition and then 
trying to run a search on the column.  Most db architects i've worked 
with make these mistakes at least once on mysql. Half of them don't 
learn and just rely on myisam and a watchdog, So generally i would say 
myisam is faster for your novice db admin, but i would agree that if you 
know how to do constraints and views properly you will leave myisam in 
the dust once you hit the 200k+ record range.
