I have a naet idea which a few people may find awesome and helpful.
The question I'm proposing [semi-rhetorically] is, Can HPTuners run from a flash drive or a Windows live-CD? My old laptop would be perfect for tuning, but the hard drive connector has sheered off the board due to wear and tear over the years. I can boot the computer and run windows off of a flash drive and off of CD's or DVDs. I am thinking about putting together a live-flash or live-CD version of Windows & HPTuners together just to see how it works. Additionally you'd get better battery life just using a flash drive as your only storage device; no spinning hard drive.
