Can I use 2 cpu's for QB pro?

In other words, can I work from my office cpu then go home and work on my laptop?

I know about the backup and restore feature, but I am wondering the following:

If I use the laptop at home and forget to backup, then I go to the office and work some more and do backup, won't I lose stuff in the process?

This happened to me last night and now I don't remember if I backed up at the office today or not.

I hate accounting..........
