Physical limits <i>can</i> be worked around with tricks though. For example google had a feature where they prefetched and started loading a result as soon as you start moving your mouse towards it to click. Latency is still there but hidden from the user.<p>Pretty excited to see what innovative tricks with predictive prefetching they came up with to base a whole company on it. I can also see this being useful for simply just files instead of apps. For example Dropbox on mobile also has a &quot;thin client&quot; approach but doesn&#x27;t do anything smart to cache frequently accessed files unless you explicitly favorite them.
