Google Earth pro, niftier than regular, go out to space, planets etc. I mainly use for street view places I can visit, or recently childhood home/family in Poland. Very cool. Only saved coordinates are S4, alleged Atlantis sites, etc.
I prefer desktop and BlackBerry (all touch). The mouse is much more efficient than moving your fingers and hand around. I tried upgrading to Windows 10 but it was tailored for touch screen, maybe missed preference to change for desktop use, switched back to 7. Can't stand Apple. That's my 'techuse background'.
