Help!! Need a laptop but which one.

Hi All,

Is the Acer aspire S7 -391 ( last years model) with 4gb ram and 256 SSD a good buy for $999.99 I want to get a portable laptop for when i travel and go on trips as well as for work. But my only gripe is as a hobby i like to produce beats via FL studio and im just not sure if this will cut it. i considered buying the newer version with haswell and 8gb/128SSD but its $1400. Should i wait until prices for the newer one go down? its not like i need it right away, but it looks so nice and who doesn't like to upgrade? Oh, Also i'm considering a 13 inch, i feel like thats a good size. Whatever information would be much appreciated.
