I also like Jake (Jacob appeals to me for mine if it's a boy), although if you are looking for arguements against it, one might think there could be a few Jakes these days due to the "Twilight" phenomenon.
I just called my little newborn Jacob. We wanted a J name and a biblical name, narrowed it down to jacob our joshua, but I hate the nickname joshie so jacob won out. DH and I did have the twilight concern, but we just roll our eyes if someone tries to be a smarty and say to them, "actually it's from another book... The BIBLE!"
