If you've got no clear goal where to go / what to do with a portable: think twice ! Portability (reduced weight and dimensions) don't come for free.
2. Are laptops good for making music ? In my opinion : no - hardly. Just the clearly above average-prices ones.. .. .. But no portable one beats a simple & sturdy at home PC in respects of value for money, upgradeability and ease of use.
PS: very good idea to set up a non-internet computer, a fully music dedicated one, btw !
