I'm investigating iBook options for my dad and am in a dilemma: iBook 14" w/ Superdrive (standard) or iBook 12" (no superdrive). He does want to eventually convert old VHS tapes to DVDs but is it better to just get an external DVD writer later? The only reason I would chose the 14" over the 12" is the Superdrive and he's keen on the 12". So I'm wondering if it's better to go for the 14" or just get the 12" for now and research external DVD writers later (more options...). There must be good external DVD writers out there that are Mac compatible.. correct? What would you do? Advice please!!!
