Hi,
for krpano itself the hardware doesn't matter - it's the browser and the Oculus drivers that want or need something specific.
About 'laptop usage' - make sure that the Oculus could be connected! So far I know most laptops are not supported because of a not directly wired hdmi-output-port and too low graphics performance.
For Oculus Rift or HTC Vive WebVR usage basically just use the special WebVR builds of Chromium or Firefox.
Best regards,
Klaus
