A quick google search should give you all the information you need...

as stated it isnt wise to uninstall it..but in vista ...you can hide it.

Also from my quick google search I found that IE7 does not have the same vulnerabilities that IE6 had...where as just having it installed ...even though you never used it....having it installed would leave you vulnerable.

as with other persons here I use both FF and IE....all depends what I am doing.
