I also really like the Honor Harrington series. I’m also a big fan of the Liaden universe created by Lee and Miller.

You might look at Robert Buettner’s first two series. Humanity gets FTL by getting invaded and using the alien ships. Good military sci-fi!

In addition to the other comments let’s not forget that IBM made the absolute best keyboards. That was not just a good thing - if you were going to replace an IBM Selectric typewriter in an office it was a requirement.
