Along with Lion Apple released new, faster, Mac minis. Of note is that there are no longer optical drives in the Mac minis — a very telling move as the Mac mini is seen as a “desktop” computer. I would guess that the Mac Pro will be the last Mac to have an optical drive and the MacBook Pros are next to lose them.
There is also a [new display](http://www.apple.com/displays/) and new [MacBook Airs](http://www.apple.com/macbookair/) which are sure to be speed demons.
Everything got a Thunderbolt port, but alas my MacBook Air didn’t get magically upgraded while I slept.
