RIP=RELEASE【巡音ルカオリジナル】+mp3♫

It was before that article was edited that it said that it was completely computer generated.

KAITO:
"The voice was supplied by Naoto Fuga"
MEIKO:
"Her voice is based on Japanese female singer Meiko Haigo's voice, which is steady, straightforward, and suitable for any musical genre."

ALL Vocaloids have had a voice provided for them & then tuned to create the vocaloids original voice

You're not completely right there. She actually doesn't care about the pain. According to the Vocaloid Wiki and entry in the Luka Megurine article...

"The song portrays Luka's true feelings of how she knew she would get hurt, yet couldn't help being in love. It also shows a slight bit of obsession as she wants to "rip and release" his throat saying that he will be all hers."

She is actually OBSESSED with the man she's singing about and can't help being in love, even though she would get hurt.

I personally think Luka is dull in comparison to Rin and Len or Miku.

She isn't dull, she's awesome <_<

all vocaloids are from samples of real people. Just that the early vocaloids like KAITO and MEIKO were not by very well-known voice ppl

really? who? I must know XD!

I'm can't remember. I think you can check wikipedia of the Vocaloid Wiki :)

Well then APPARENTLY you don't know the official information, as KAITO and MEIKO are both completely computer generated.

Wow, this is actually one of the better vocaloid songs I've heard that doesn't sound battered to hell with notes flustering all over. I rather enjoyed this one.
