[Ubuntu One] is ideal for people that have an Ubuntu netbook or laptop that they use regularly in their garden or on a terrace.
Not unless your connection to your ISP is a hell of a lot faster than mine it isn't (and if *that's* true, it's probably metered). For this application a simple wifi network and a frontend to rsync are surely preferable.
Where cloudy things, er, shine is the ability to sync possibly many systems to many other systems that are a lot further away than your garden, without needing to set up authorization between all the sources and all the targets. This doesn't really strike me as a terribly common use case, but then I don't even use gmail so I'm obviously stuck in the past with a bizarre desire to keep my private data private on systems I control. :)
one or more nodes (servers with a KVM hypervisor running virtual machines).
Given that, it's a shame that, in x86-64 Ubuntu 9.10, at least one of the video drivers normally best suited for KVM (vmware) carries out SSE2 operations (at least it's probably the vmware driver). It's quite entitled to do that (SSE2 is part of the x86-64 ABI), but KVM doesn't emulate SSE2 instructions yet, so kicking up an Ubuntu 9.10 instance leads to massive CPU consumption and logflooding with 'emulation failed' messages (thankfully ratelimited or there'd be hundreds of thousands of them a second).
