I have a laptop I carry everywhere and amps both at work and at home. I also have a little drum machine. I want to start recording these doodles I come up with. I can see a guitar in the future so let's just say I may need 4 tracks. In the future I may find myself living on a cramped ship or on the ground in the Middle East as well (knock on wood). The bottom line is I need portability and will probably sacrifice flexibility for it. I'm debating between a USB device like the Line 6 or M Audio products or one of those Tascam or Fortex all in one hard disk/ flash memory recorders. Pros I can see for laptop and USB device: Less weight, availability of more software tools, capabilities can be increased via upgrade. Pros for all in one: Very easy to use, guaranteed to work regardless of hardware configuration, hardware vice software processing(at least I think so). So what do you gurus think? Also, are there any gotchas or surprises I need to know about both options? Don't be shy to throw out your hardware recommendations but please keep it under $300 Thanks!
