Apple brings out a new model every 3 months and people line up overnight to buy it.
Some of these gadgets may be tech high but just stupid. Read this tongue in cheek mini article on how smar phones can be stupid.
Blue Fox 2: Silliness of the Stupid Smart Phone
There could be many reasons:
1) This feature could be very helpful in mobile phones made for blind people.
2) What if the user is an illiterate who just knows how to use the dialer and make & receive phone calls ? This feature could come in handy a little bit.
3)Assuming SMSs are free and voice messages are not what if you are driving and you receive a message, text to voice could be handy, no ?
See nobody is forcing you to buy a smart phone at gun point! If you don't a see a feature useful then don't buy that phone. If everybody does this then there would be no demand for features that are really "silly". Then automatically developers will stop coming up with silly features....Who really knows ? What if that developer was really bored and had nothing to do at home and came up with that app ? This is still better to me than writing a silly stupid blog and not doing anything!
