I bought Jolla tablet.

I see no need for 3G/4G for me. I take tablet with me outside the home only for really long trips where I have to do traveling with train or plane. Usually there is wlan availeble at least by sharing connection from my phone or then there is no connection so having it availeble in the tablet would do no good.

I personally dont like to carry big devices with me. For example, the screen size of n9 is perfect for me when outside my home. But everyone has their personal best choices. And also if the option would be cheap, i would probably also support it, just in case
