Hey Ryan, in practice most of the stuff you mentioned is actually double-insulated, so it wouldn't even matter to connect it withouzt a GFI. A ground is definitely _not_ necessary for technical reasons. Where would it go with a 2-prong plug? IT equipment does need a ground, both because it often comes in metal enclosures and for static discharge. For the latter reason an ungrounded GFI is not good for this kind of equipment.
