4G network - I use my phone as my home wifi. I live out in the middle of butt-fuck nowhere (even by standards of Finland this is the middle of nowhere) and the only copper-wire ISP that services this area is able to provide only the bare minimum 1Mbps connection. On the whole I'm happy with the 4G net -- except that I live fairly close to a military training ground and everytime they do field training my internet goes to absolute horseshit. Luckily it's only a few times an year and for a few days at most.
