Yea, unless you're into gaming, or CGI modeling, there's really no Earthly reason why you'd need one.
Frankly, I wouldn't even dream of buying something that expensive unless I had oodles of money lying around anyway. I only bought my last one because I had just got back from overseas, and had over 30 k sitting in my bank account. lol
$400.00 sounds like a good deal.
