We all know Simon Pegg is a great comedy actor, up there with Ali G and Borat as one of the all time greats, and it is absolutely physcially impossible to imagine him talking in a scottish accent without laughing. Just try. I just tried!

That's what happened. I started laughing and looked just like that smiley. (I'm not green and I don't have pointy ears, I should point out, but the laughing was so me.)
Since this movie is NOT a comedy, why not just make Scotty English? Britain is a tiny island anyway so there isn't much of a difference. Scotty is only his nickname because his name is Charles Montgomory SCOTT. I mean, if they changed Kirk's home state from Iowa to somewhere else nobody would care. Shatner spoke with a Canadian lilt in TOS and I'm sure Chris Pine won't speak like that (I HOPE NOT ANYWAY.) I think we should be flexible and prepared for accent changes.
