I read both specs. Aside from the color of the cabinet, I don't see anything that's actually different from one set to the other. $500, on the other hand, buys a lot of beer, DVDs, etc. Seems like an easy decision to me.
Unrelated easy decision of the day: a friend of mine is considering getting into the whole digital SLR game. With B&H prices, a fully decked out Nikon D70 kit (w/ lens & 1GB card) costs $1000. The same exact setup with a D70s is $1300. The differences between the D70 and D70s are largely inconsequential, while $300 gets you a flash, another lens, or whatever.
