How to keep horse records ?

Hey , what software would you recommend for keeping horse records ? I am using a laptop and windows 7.

I just you a spreadsheet, e.g. Excel or OpenOffice.

I guess I am old fashion. I have a hard folder and put all my receipts and medical papers in there and 1 a week make a written out copy of what needs to be done.

If I put it on the computer I would forget to update it :(
