So I already posted in a thread to sell my machine because I want a more portable machine. The MacBook Pro is an excellent machine by all means, but again I want a more portable laptop. The only thing I'll be doing on it is taking it to classes to take notes, surf the web; maybe watch a few movies when I don't have access to my desktop. Now the issue is, will the machine be powerful enough at the same time? I'll be buying the 2.13GHz model. It will be bought at the Apple Store, so I guess I'll have the SSD as well. What's the average battery life I should expect out of this machine? Would a 13" MacBook be a better choice in any way?
