This (old, heard it even if you didn't say it!)guy is/was not suggesting people go "totting" for old computers! I merely meant that SINCE the OP had an old pc it made sense to use it and ONE good use is as a secondary backup, my point about usb drives being that I have had them fail,twice in 3 months but I have only ever had one internal HDD fail in 6years and that was only days old! If you have ever had serious problems with a pc you will know how vital it is to have a spare!
I think the power/greeness/tree hugging is done and dusted?
Er? And yes, a laptop can do almost everything EXCEPT run a serious music setup!Laps are also I would think even less planet friendly than big jobs? Hard to fix and batteries you know!
Its probably different for film composers and people who record bands, but you may be shocked at the big names who use a MBP for their main DAW! Makes sense too ... can make tunes on the plane, in the hotel, get back to the studio and hook it up to the big monitors. Keep a time machine backup and if you lose/break it you will be up and running again in a couple of hours ...
