Should I buy Avatar on Blu-Ray?

Avatar was released today in Ireland and I was thinking of picking it up. I'm not sure if I should get  it on blu-ray or not. I have only one blu-ray player (my ps3 in my bed room) and a  dvd players in my living room. One of the down sides is with blu-ray is that none of my friends have blu-ray players so I can't really bring it out and watch it with friends. What do you think I should do?

Hold it.
 
The better version comes out in November.

If you like buying Horrible movies why not...

No.  Buy a giant brown bag of candy instead!
