Yeah I can see how the 2 inputs could become restrictive, thankfully our drummer has a rich friend so band recordings can be done there.
I'm trying to sort out a laptop at the moment, the macbook looks lovely although I don't think I can really justify the extra cost. Looks like it will be a Lenovo I end up with. Mind you I'm using a 1.5ghz Celeron Toshiba at the moment with Live and it runs a lot better than I expected!
