Just some tidbits about the lingual enhancer.
This is the dialogue between Mrs. Bishop and the PC regarding it:
PC: So you got your education in Vault City? That's why you sound different than everyone else here in New Reno?
Mrs. Bishop: They had memory enhancers for the Pip Boys there. Had dictionaries and encyclopedias stored on them. Took one of the lingual enhancers when i left, though i don't know why.
PC: Where is this enhancer?
Mrs. Bishop: *Yawn*... (curls up). It's in my safe. Not much use without a Pip Boy, though. Don't know why i still keep it.
PC: Can i have it?
Mrs. Bishop: (Shrugs) Sure if you want them. Combination is 70-50-71. The enhancer is in a compartment in the bottom of the safe... A thief isn't going to find it unless they know what to look for.
PC: How do I use it?
Mrs. Bishop: Just attach the headgear, place your optic sensor over your right eye, then connect the other end... hmpphh... (Rolls over). to the Pip Boy. You'll feel a slight rush, some nausea, then your head will feel clearer.

And this is the description of the enhancer itself:
"The Pip Boy lingual enhancer consists of a storage holodisk, a microfilament cord, headgear, and an optical sensor that is placed over the user's right eye. When used, an optical flash transmits an entire dictionary into the user's memory, permanently improving the user's speech skills."

So, i believe its safe to conclude that:
>Lingual enhancers introduce knowledge into a person's memory directly, therefore the need to carry one at all times is rendered useless as it doesn't operate via a boost to memory as long as you wear it. It transmits directly but its obviously a one-way transmission.
>Mrs. Bishop states she got her education in VC, and apparently with a lingual enhancer. If a lingual enhancer was common in VC, and if by your logic, it was permanently "implanted" on someone, every VC citizen would have one. Yet, this is never mentioned, and also, even Linette doesn't wear one. No records of it exist in the medical computer databases, also.
>If the lingual enhancer was implanted, it couldn't possibly be used on the fly because obviously, the PC doesn't have the means nor the tools to implant something onto himself. Quite likely, like other implants, you'd have to undergo surgery by a doctor that knew the procedure.
>Also, note how the headgear is
attachable, not inserted or implanted, or anything similar. For it to be an implant, it would have to be implanted (i know this is common sense, but some people are impervious to it).
