The Travelmate was OK but she found the touchpad very difficult to use, it's one where the 'buttons' are not actually separate from the mouse movement touchpad and she found that very difficult.
I have an Asus something or other running Debian. It has a buttonless touchpad. Completely by chance I found that it responds to the Mac way of scrolling: two finger swipe. Previously I'd been struggling with clicking and scrolling at the same time because it didn't understand that the bottom area of the pad was the buttons. Suddenly it became a whole lot easier to use.
