You might find these two words easier to understand if you browse sentences with 一緒 and同じ on http://jisho.org/sentences/ (the sentences get longer/more complex as you go through the pages)

I'd explain how I see them as different but I don't want to risk giving wrong info.

Hope the link is helpful

I think the key part of that definition is から, indicating that it came from Kansai-ben. I think it's common throughout Japan (now) and most of my dictionaries don't even mention Kansai in the definition.

Jarvik, you're right!  I done got overzealous with Kansai pride.

Here's what I asked:

「一緒のやつ」と「同じやつ」の違いは何？

Here's what two friends said:

Pal #1: うーん、ほとんど同じやなぁ。。違いはあんまり見つからんかも。
しいて言うなら、「同じやつ」は、何々（物）と同じってことで、「一緒のやつ」は誰々（人）の持ってるやつと同じって感じかも。
でも両方人にも物にも使うから違いは全然気にしなくていいと思う！
「やつ」がついたらどっちもsame as~の意味になるよ。


Pal #2: 同じ意味よ。
「同じ」の方がアカデミックに聞こえるけど、「やつ」がついとるからなぁ

Two completely different answers.  なぜかいうと、たぶん日本人は意識せずに使ってるからかな。　This really bothers me though because I will usually say one and then someone will use the other when they reply, like captal mentioned.  So I don't know if I am being corrected or not
