Returning to Wombat's big question one more time, there is another rather good reason for
basing a DAW on a 'portable' (and I'm assuming what is meant is a laptop and not some
little pad): Laptops and notebooks are being offered more frequently with many or all the
bells and whistles of those dinosaur desktops. I am planning to buy another laptop within
the year that I can dedicate solely to audio, and I was just looking over quite a few that
now have 7200rpm drives installed and about 750 gigs of storage. Recall, too, that they
can run external drives just as well as desktops for those requiring more space.
I really don't see that it is any kind of issue. I began my trek in personal home
digital audio on a nice ASUS laptop. All this time later, I'm still doing just fine, thank
you! Besides desktop computers are not only bulky -- they are perceived largely as 'dogs'
these days. Not cool. No longer needed.
