Go with the 32gb or 64GB.

(I think my math is correct)) If you get a 8GB its like paying $40 per GB vs the 32GB $10 per GB.


iOS4 is approximately 2GB. vs previous OS 3.1 1.5GB

The 8gb has 6.5gb
The 32 has 29
And the 64 has 59
 
Honestly, if you're going to shoot any video at all, or consider putting movies, you should go with the 32GB.
Just saying! 😀
