Problem:
Computatrix, a computer retailer, sells a new computer to Davina on credit. Davina buys the computer for her personal, home use. Computatrix attaches a security interest on the computer but does not file. Shortly thereafter, Davina sells the computer to Boulder for $2,000. Boulder buys the computer for his own personal, household use and also buys without knowledge of Computatrix's interest. After Davina defaults on her debt, Computatrix tries to reclaim the computer from Boulder. Will it succeed? Why or why not?
