I can finally upgrade my G3 machines to MacOS X, because my SE/30 is complete and ready to carry on the System 7 torch!
The 40Mhz Turbo040 is rocking out and powering it along, the 80MB of ram is more than I'll EVER need, and networking is a breeze over the ethernet, both in 7.5 and in NetBSD. DragAnyWindow is totally necessary on a 9" B&W Mac, and it's great to have a two-button mouse--set the left button to the "drag any window" key.
Sorry for spilling out here, I just thought some people here would be excited too--I know I always love to see people brag about their 68k machines!
Keep on Mac-ing,
