Thanks everyone for the info, I needed to know if "non-mobile" sites would turn everyone away who is on a tiny screen.
I got very used to acces almost all kind of websites from my smartphone because I use it for online work more than my computer. So I have no problem to use websites that are not mobile friendly because I have used a lot of them and already got used to it. I also have a computer home but don't use it a lot, only if I want to complete something faster and easier.
I try to get used to my phone, but a desktop is much more comfortable.
