I have used Mosh as my primary remote access client for a few months on my "on-the-go" laptop, and I must say that the user experience is very good.

In a lot of scenarios, the latency is not much of an issue, but on wlan/3g, this very fast become very noticeable. In the few cases since, I've used ssh on wireless, I suddenly find myself noticing how much of an issue the sudden feedback delay might be at some times.
