Forgive the lack of a U in my spelling of favorite. I'm a yankee living down here in NZ :P.
As I'm sure many of you know there's no dearth of remote access software out there now; pcAnywhere, GoToMyPC, LogMeIn, TightVNC, radmin, Microsoft's own Remote Desktop, and any number of home-brewed, open source programs out there. Some are free and some aren't, and some have features that are not to be found in competitor's versions.
So what are your favorites, and why? Personally, I use logmein since we use that at our offices (i'm actually using it to type this), but I was a gotomyPC guy in the past. The things I like about it are the web interface which skirts the whole issue of dynamic IPs and the fact that our customers are so receptive to it.
Let me know what you think!
