Re: the Cloud
Oh, alright then, The Cloud is a catch-all term for applications and services provided on distributed systems, as well as certain implementations of multi-site redundant server virtualisation, and file storage. Saying that something is "in the cloud" is roughly analogous to saying that it's "on the internet" - both terms are vague, but imply that "it" (be it a file or an application) is in a location away from the device, and accessible via the user's internet connection. The Cloud is also the brand name of a WiFi hotspot provider, but this is usually not what someone means when the refer to "The Cloud".
Bleh. That was a mouthful.
Quick, everyone down The Pub (but don't specify which one!).
