OS X 10.5 not coming until Fall

I guess it's not a big deal, but the next major update of Mac OS X is delayed until October. It seems odd that the reason is that so many resources have gone into getting the iPhone ready for release in June, but Apple isn't really so big that they've got enough people to manage all these products at the same time. At least that's my guess. I'm disappointed a little bit because this will also delay the purchase of new hardware unless they offer a free upgrade on the software. It will also delay the new version of iLife and possibly other software. Six months isn't that long, but in technology time, it's a whole generation.
