ok, i'm praying my sarcasm detector is broke and this whole thread is a joke, but if not, you guys are scaring me.
For the cup holder:
1. A full cup would put a ton of undue pressure on the tray of the CDROM. One too many uses and *CRACK* there goes your cd tray. They are very fragile all things considered, and they are only meant to support the 2 or so ounces a cd weighs.
2. A cdrom tray has NO BOTTOM. What would you put in it? You could put a styrafoam cup in it and that's about it. Everything else would have to either rest on top of the tray which is not really "holding" anything (isnt that the point?) or couldn't be used at all since it would fall right through the tray if it was small enough.
I'm just stopping there, crappy weather today has made me grumpy. I just don't get the point of this, it would be nothing more than a cd drive that pops out the side of your cabinet just..... just because.
And I also love the buttons in the cd tray idea, seeing as a leafswitch and microswitch are both more than likely bigger than a cdrom tray opening....
The ideas are awesome, but they both seem like they'd be so much work to get up and running, that it isn't worth it. Buy a 3 dollar cup holder and put some buttons under you CP. Done deal.
