Got hooked on computers in his pre-teen years and progressed from Commodore 64 and Sinclair Spectrum to DOS/Windows PCs. Eventually saw the light, bought his first Mac in 1998 (the original Bondi Blue iMac) and never looked back. Addicted only to legal drugs, 70% cocoa chocolate and pure green tea.
