That's not ideal, of course - the point of the Web is that you can visit a website from anywhere - but in practice, when this type of cutting-edge application arrives on the Web, often at least initially it doesn't run optimally in all browsers or has other limitations.

In general, after the initial launch things tend to improve as both browsers and applications focus on compatibility.
