Ok im very limited on money and i need a mac for school. I was hoping on a macbook but its just not a viable option at the moment. I really dont do much other than internet, ripping cds onto my ipod, and school work. And i have a digital camera as well. A superdrive is not too important right now, so looking at the minis, is the duo going to be a huge difference for me? Also is the solo basically a centrino? I know a 1.5ghz centrino isnt too quick. I have a 2.4ghz p4 in my compag laptop that has been giving me trouble. I do want a boost in speed over this computer. My question is, is the Duo Mini worth the $779???
