Well, I guess it all depends on your circumstances, team size and other factors as well. Working on a small hobby project with friends is an entirely different situation than having a larger team of paid professionals. I assumed Hussam was in the hobbyist category, since he doesn’t seem to have heard of SCM yet.
I’m in the hobbyist category myself and decided to set up a server, because we wanted to use P4 and $25 a month is a lot, if you’re still just playing around in your free time.
Really not a problem for a small team and a hobby project. Internet speeds are quite nice in Europe.
I can’t. But if I had to, I wouldn’t host the repo on my crappy old macbook 
Also, our productivity is probably more affected by exams and less by server down time
