How is it better? Comp/software v.s. Dig. 8track record



I know I can get a digital 8 track recorder, say BOSS for about $800 Can. and a decent condenser mic for upwards of $200,and I would have to get a cd burner unit for a few hun more at least.
But how does it differ from a computer set up built solely for audio recording, mixing?
What would I get (or need) to build a dedicated box, and how much is software for a decent set-up?
Of course i would need a mic still (or more) but can i get anything for the 1100 it would cost to get the 8 track/burner?
I need the basics too here people, I am not really up on lingo. hee hee :cool:
