I've been using logmein for over 5 years and although at times I was tempted to go Pro, I stayed with Free simply because there was no need for it. The free did wonderful job. I was able to login to my computers from iPhone, Mac or PC without firewall or dynamic IP problems (stuff that use to matter back then). I always wondered why they did not charge this awesome product. I do not mind paying for the service now but I wonder how will this impact less frequent users who wants to fix their mom's computer once a year or so? They say join.me remains free but is it as good as logmein Free? I had mixed results with it.
