I’m not going to spend a lot of time on these rumors because I don’t really believe a lot of them, so instead I’m going to link to information about them.

(after each rumor I’ll say believe if I believe it, I may contradict myself, when you click through, but what is listed here is what I believe now, my views may have changed since I wrote the post)

3G iPhone shown at WWDC (believe)

OS X 10.6 Snow Leopard (believe)

.mac turns into Mobile Me
16:9 MacBook and MacBook Pro LED Screens

I plan on continually updating this post as new rumors come out, linking to them of course. So, check back periodically to see all of the new rumors that come about.
