Well, you may have noticed my earlier post asking about mastering software, but since this seems to be a related topic.
I gave alot of thought into this PC versus portable decicated DAW routine and decided to do the following:
Tascam 788 for recording etc, Echo Mia (24 bit/96kHz) with digital ins to the PC, and undecided mastering software.
I have spoke to several buddies who are into DAW stuff, and we even had one come out and record one of our shows. He had to bring all kinds of stuff.
For me, the portable for recording PC for mastering seems like the best solution. As previously stated, I can be ready to record in seconds, don't ahve alot of crap to worry about, and can carry it in a gig bag.
Later, I can digitally transfer it to my PC for mastering, adding more track, etc. then burn CD's. I can premaster the stuff on the 788, or leave it alone, whatever I chose.
some of the guys that I know have said that they wished that they had done the same when they went about it.
But as with anything in life, it's what works for you
