I use it on six different machines and have for a few years now.
LogMeIn is an excellent alternative to GoToMyPC. We have special needs which require scripting and so will be using another product. But I urge everyone on this forum who is in business and uses GTMPC to abandon its terror-coddling maker, Citrix Inc., in favor of ANY other solution.
I reiterate, as of Jan 1st 2008, Citrix will have approx. 2,500 fewer licenses from us alone, with more being removed as the year progresses. We simply will not do business with a company like Citrix, which has endorsed an anti-American, racist and terror-supporting organization like CAIR.
