The name might be LogMeIn, but the motto should be SignMeUp.
The fact that it's free to use for multiple remote PCs, with reasonable monthly plans if you need more--five computers for $20 per month or $200 per year--makes this remote-access program instantly appealing. The program differs from its competitors in that the application runs in your Web browser. If you're running Firefox, it asks to install a plug-in, then opens an emulator of the remote PC in a new window.
The control window gives you some standard options such as Ctrl-Alt-Del (which kills the connection) and changing the view settings, as well as tabbed access to adjust the connection setting. The 256-bit SSL encryption and dual passwords--one for the program and one for the remote PC's log-in--are welcome protections. File transfer and synchronization features are limited to paid users, but for the functionality and the price, LogMeIn is an excellent program.
