OK... after hearing about how good BIAB and RealBand are, I'm on the cusp of buying them. However, am I to understand that if I order the UltraPac it would come on an 80gb external hard drive or discs? I'm thinking that if indeed it comes on the HD, that would be the way to go... however, if I ever have to re-install Windows after getting a virus, (this happened to me last year) wouldn't the discs be a better way to re-install BIAB and RealTracks? Is this stuff really THAT big? Wow... How things have changed in 15 years. Back then BIAB and PowerTracks came on a couple of 1.44 floppys.
