Good for marketing department but, who cares when all you have to do is format a memory card.
A small price to pay to extend your memory with 64GB / 128GB vs having to buy a new device because you ran out of memory, isn't it?

I am a little bit surprised to see this kind of stretch goal taking Sailfish fans for dumber than they actually are.

About the other goal: 3.5G

In particular the cellular connectivity has demanding certification and field testing requirements.

I don’t want 3.5G, do I have to upgrade? No, you can still have the original Wifi only Jolla Tablet, with the original delivery date of May 2015.

With all that field testing they may as well give it full telephone functionality.
This is not USA where the goal of iPad 3G is sell another SIM card for master Telecomoperator.
Or is there some cost inducing European license issue that I am unaware off that forbids tablets to be phones?
