If I open iTunes on Windows and scroll through my music library (~20,000 songs) then move over to Google Play in chrome 28 and scroll through the same library, I notice very quickly that the native experience is undeniably better. I would estimate the total lag (between spinning the scroll wheel on my mouse and seeing the ui begin to scroll) is about 10 times as long on chrome. Another example: try using any web based spreadsheet software after using Excel for a while. I guarantee that you'll be immediately frustrated with the web apps sluggishness. Web apps are getting better, but anything that uses both the HID and graphics stacks is still way faster if native.
