Take this for what it’s worth which may not be much.
I work in higher education and was talking to our Apple campus rep last Friday. I was saying something about how I was finally going to trade up from my Pismo to a new 800MHz TiBook and was just talking myself into writing the check.
The rep said that, as a friend, I might want to wait until after July since the TiBook form factor was getting a tad old and, after all, Apple tends to make their big form factor changes in July or January.
Just as a friend, you see. Suffice it to say I’m going to wait.
