Safari on a PC is very, very weird. Leopard is kind of groovy. The new dock is cool and the Stacks are a nice concept. But I can't help but say that it has a Vista-ish feel. I don't know. I'll probably end up taking back what I just said once I try it out.
I got myself a Nikon D40 the other day and I'm really excited. His name is Henry, but you may call him Hank if you'd like.
The D50 is wondrous, I'll have to check out to new stuff in the D40.
