Did MS run on Macs even 4-5 years ago? Because, based on straight MIPS/Gflops calculations, the current iPad Air/mini retina is basically equivalent to CPU/GPU power of PC's about 5 years ago - and gaining fast.
I guess I'll stick with my BIAS amp, MIDI guitar, iOS synths, Audiobus, Apollo, MIDIbus, etc. configuration for live gigs with iPad and leave all the DSP and amps back in the studio
