"GNU/Linux Terminal" of course! :-)

I vote for keeping the icon. It's not like there aren't lots of other icons in the apps list that most people will never use and never find out what they do.

X-Terminal is the most used icon on my desktop and occupies a prominent spot. I use it more than Contacts, Phone, Calendar and Conversations, because I use the terminal to read my email.

If I had to type an awkward key combo to read my mail, that wouldn't be very convenient at all.
