That's what I did- just ordered myself a TiBook.
I vaguely remember using 10.0 on iBooks my middle school had back in the day... back in the year 2001? They ran OS 9 normally but I could get sneakily get around some security blocks if I started in OS X by holding down the X button.
I forgot about the extensive pin striping. Maybe Steve Jobs was a Yankees fans.
I grabbed a Gigabit TiBook for the same reason. That shipped with OS X 10.1, which is very very limited.
