I saw the Hackintosh stuff a couple years ago. I'm a professional computer geek, and I'm tired of fiddling with multipurpose platforms and keeping them running and yada yada yada. Mostly I just feel that mouse, keyboard, monitor, and the desk they sit on do not mix well with guitars. Now that my kid is a toddler, my free time is measured in chunks of minutes and fractions of hours.
I'll probably continue to research and vacillate until I pull the trigger. But I'm kinda thinking the R8 is actually enough for my intended use case. If I NEED to record 8 tracks at once, cool beans, it's a great problem to have. But it's hard for one person in a bedroom studio to generate more than 2 tracks at once anyway. My envisioned process goes something like:
Set up click track:
Throw down scaffolding rhythm track.
Bang out drum track on cajon
Record bass track.
Replace/Augment banged out drum track with drum machine.
Layer everything else, replace rhythm track if need be.
I'm still missing my pickup for MIDI guitar. But I have a keyboard. I'd still rather play it on guitar. But I can always record audio instead of MIDI for synth stuff.. I kind of think I like that idea better, both in terms of work flow and not spreading my skill set too thin. (ie, if you're playing midi guitar, on the guitar, and you're rerecording till you get it right, rather than spending that time reading manuals and playing the musical equivalent of Tetris on a piano roll .... it's all goes back into the "becoming better guitar player" pot instead of dabbling in piano roll editing and manual reading.)
