Andrew,
Yes, the solid state drive has no moving arts and saves on energy and heat as well as wear and tear, that said it's a fortune! I just bought the older model MacBook Air from MacMall for $1,149, for me, the 80G HD is enough for my laptop uses, I keep all my music on a separate HD on my main computer so when at home I can access it with the laptop if I want to. Either way, the 120 or 128 G HD is likely too small for a real music collection and you'll need an external drive. (my music collection is over 600Gs!)
