Pioneer A05 - Internal vs External...

[spy]

Hi - I plan on purchasing the A05 Pioneer DVD-RW drive (Internal), but I am also thinking of going with the Pioneer 105 (External) Drive... They have the same speeds, and are practically the same, except for a difference in price, but what I wanted to know is if there was any advantage/disadvantage to go with an external? Or would it really make no difference at all. I like the idea of having the drive external, or portable, but if anyone could tell me why I shouldnt get it it would help me out. Thanks.
