hi, i am looking to buy a surface for kind of replacing my older macbook. This isnt to be my main computer becuase i have my desktop that i built. the surface pro 1 128 gig and the pro 2 64 gig are around the same price. the only difference that i see between the 1 and 2 is that the 2 has a slightly better cpu. is it worth it to pay a little more and loose all that storage to get a slightly better cpu in the pro 2? thanks.
