What does LogMeIn Pro do well? LogMeIn Pro works on any system. The software is reliable, we haven't had any real issues that weren't handled immediately which eliminates frustration. I have been able to access my desktop worldwide without any issue in the past seven years. We have had it adapted in the office as well, but it was only a short-term situation, as such, I don't feel comfortable talking about the software in a commercial environment, but for personal use it's fantastic.
What does LogMeIn Pro not do well? Mac to PC can be frustrating. Copy & pasting from remote PC to any Mac can be problematic as the clipboards don't always want to be friendly and sync up and/or pastes in different formatting (adding spaces, removing line breaks, etc.). Also the keyboard mapping can intermittently goes nuts from Mac to PC, requiring a closing and reopening of the remote session. Not impossible, just a bit finicky.
What do you wish you had known about LogMeIn Pro before using? As with most fantastic software, I wish I had found it faster than I did. They could advertise themselves more so the people not in the know (like myself) would have a far easier time in life!
