Somehow you managed to get a negative Nerd-Factor. So I'm afraid, your NO NERD AT ALL.
You don't even know the most basic nerd activities!
But all is not lost: Quit what ever you do and start doing nerdy stuff!
I am the bomb!!!!! :-D
I don't think the upgrades are too expsensive, you just need to know in which order to get them. If you choose the right order, it doesn't really take long to get more cash to get more upgrades.
