When you are at a hotel or coffee shop and connect to the public wifi you don’t know what is lurking on the other side. I consider it unsafe.

Then add a guy like me that has a development machine and quite possibly a port that I have forgotten open. Plus some web sites in different stages of alfa and beta with all debugging info turned to 11. That is unsafe if something.

So I use my phone as hotspot. But why should I? why can’t I use my phone as wifi to wifi router? I know I have a certain small Win7 machine set up as wifi-wifi and wifi-3Gdongle machine so why not my mobile phone too? It would save me a bill abroad at least.
