I’m on a MacBook Pro as well (2.33 GHz Core2Duo), but can’t say I’ve noticed the OS or accompanying apps being much snappier. Not at all slower, to be sure. But that’s just probably a perception thing on my part.
There are some problems with Adobe apps, mainly Acrobat and Distiller, that will prevent me from putting Leopard on my office machine for a while. (I do lots of print production work as well.) But I’m enjoying it on my MBP. There are some bugs, to be sure: RSS is wonky to the point of can’t rely on it; Mail’s sounds don’t always work; it broke PGP. Little things like that, though there does seem to be more of them in 10.5.0 than in 10.4.0. I’m assuming many of those will be squashed with the 10.5.1 release.
I’m thinking that will be relatively soon, because I want to recall there was a 10.4.1 release within a couple of weeks of Tiger’s initial offering. But I could be wrong. 😝
Not denigrating Leopard at all. There’s lots to love. I’m particularly liking Mail’s new notes and “to do” functions and look forward to putting those to work on my office machine. The new TextEdit will open Microsoft’s latest Word format. (So will Pages.)
All in all, as it matures it’ll be the best yet.
