Yes I feel digital dairy r worth the price.they aren’t expencive ut cost almost 1200/- rs for a light enabeled 128 kb digital dairy.in 128 kb u can store as much as 3000 phone no. with name and address.it is very good for people who move a lot from one place to another.
it is so small and handy yet can give u information about thousands of phone no. just at a little click.as it has search function , finding name and information is not a problem.
one thing I donot like about digital dairies is the require a lot of battery.after every 1 1/2 yrs you have to replace a battery.each battery cost as much as 60 rs and you have to replace 2 at a time.
i prefer casio over sharp in digital dairies it is more user friendly like windows over mac.
