Wikipedia has a Mac timeline that is sweet! You can view all of the Mac’s made since the beginning of Apple. Click the link and get the Wikipedia page for that model. It’s pretty neat!
MacWorld has a good article on modding your Mac. Complete with links and more on how to do it, who should do it and why.
Worth the listen.
MacDevCenter.com: has a good article on getting ready for Tiger, which I may not get to use until Monday 🙁 But I have already used SuperDuper to make a clone of the drive (worth the $20 in my opinion). I can boot off the FireWire drive if necessary.
I am looking forward to this release, but am like others sort of skeptical, since this is the first major OS upgrade to my Mac.
