I still think the buttons are too small.
The original Nokia 3310 had small buttons, so adding big buttons may cause fans of the original phone to not buy this phone to collect, or use as a basic phone because they enjoyed the portability and design of their older 3310.
If you just need to make a few calls, and save most of your important numbers to your speed dial address book app on this phone, the small buttons are not a big deal for some people. I used an old Nokia phone similar to this phone many years ago, and it was good enough to make calls, type short texts, and play games like Snakes.
No. Just no. Even senior citizens can learn to use a basic smartphone nowadays. I know people in their sixties and seventies who use touchscreen phones. There's really no need for these on the market.
Some people may buy this smartphone as a collectors item like how some people buy old iPhones, and Blackberries to collect for fun. It is better to buy a Nokia 3310 from Nokia than a clone/copy version from a less trustworthy company.
Other people just need a affordable durable cell phone for calling people, and replying to a few short texts. Many people already own tablets which can use apps for iOS, Android, etc, so not owning a smartphone may not be a problem for them because they can use the same mobile apps and games like Temple Run on their tablet.
