I went over form 8910 again to verify the personal use issue. It clearly says that the credit applies to business use and personal use. The catch is that this form is old. Last year, AMT messed up this credit for personal use. The 2009 form appears to have removed that condition (as stated by Penguin several posts earlier.) The 2009 form can be found in Turbo Tax (not yet posted on irs.gov.) I see the full credit with no regard to AMT for personal use.
