Laptop mapping software

I'm using Streets & Trips 2013 on an old XP laptop. I was sorry to see MS end S&T's run, for I have found it very easy to use. I have it installed on both an old XP machine which is mounted on my console and serves as my navigation aid, as well as my main laptop. I do my trip planning on that machine and then just copy the trip to the other laptop with a USB memory stick. Being 3 years old, it occasionally sputters when I'm on a new road not in its DB, but that is fairly seldom. I tried a Garmin, but found the small screen hard to see and I had a bad time trying to plan a trip on it. The 12" screen is very easy to see and I like the ability to quickly and easily zoom in and out using the plus and minus keys.
