Ok, finally pulled the trigger and purchased an OctaCapture today (but it won't get here until next week sometime). I will report back on its stability on the HP Envy. I am really hoping I can track 6-8 inputs simultaneously and without dropouts since a friend of mine wants to track some grooves on my Gretsch kit. Not sure if the notebook HD can handle that so may need to add a SSD in the Envy eventually but for now crossing fingers that I don't have to spend more money!
