Apple needs to upgrade to a 32/64/128 GB standard. 16 is way too small now and it shouldn't cost 100$ to upgrade to the next level! I can get a 16GB flash drive for 20$ and 32GB for 30$. Flash prices are way down and hopefully Apple uses that to lower the prices for its customers
I think Apple should go for it. Doesn't hurt to have a larger phone in the mix. Looks like they are quite popular.
And when Apple is late to the party, they always bring an amazing designed device with them so it will be exciting to see how they do it
