You should really only use 'is' to check for object identity, and for any kind of value comparison, == is the way to go. Also, as you yourself point out, the changes you made make no difference at all, unless there are non-ascii characters in the string you are comparing the variable to, so in the case of 'textarea', I would have just left it as is. ;)
