Before I get misinterpreted for...
I'm not saying one thing, then contradicting myself later. I'm okay with ZIP drives being fitted in a mac IF:
-The owner of the mac/computer does a clean job at the hack (NONE OF THIS!)
-If possible, the hack can reverted back to stock configuration, should Zip go TU in some horrible way or you just don't want a Zip drive anymore.
Like said, it's not OUR mac to say what can be done with. It's HIS. Our only concern is that there's been a few mac hacks which orginally looked REALLY nasty but got a lot of attention and later revisions that were a lot more cleaned up but did not get the same amout of time in the spotlight. The idea is that if it's clean from the start it's okay for future attempts to be a bit more messy.
