I'd like to talk about computers and interfaces, and which programs work best with which Operating Systems.

1- Why interface? What's the point if your computer has a sound card?
The best DAW I've found is LogicX, but Apple's new computers don't have a "line in" any more... Isn't an interface just an external sound card with gain controls and input options? My mixer does that and my old sound card works just fine. So, aren't interfaces just a "gimmick" to sell more hardware? Separate stereo line-in and mic inputs used to be standard on any computer.

2- LogicX comes with absolutely everything you need, including a very easy to use drum program for only $200; If you can afford the computer lol. So, are there any comparable Windows based programs that won't keep "nickel-n-dime'ing" me for annual account and upgrade fees?
