My daughter got some low-end Dell laptop for her school machine and the touchpad w/o buttons is fucking excruciating. They had her using OnShape last year with that touchpad. I tried it and nearly gave the machine a toss in frustration. I had her use my older Dell machine w/ buttons to see how much less shitty it is (and then I gave her a USB mouse to use because OnShape with any touchpad is still difficult to use, IMO).
