Cloud computing is fine for people with fast, symmetric internet access available at all times.
In the UK, the reality is slow internet in most places, adequate download and poor upload speeds in some places and fast internet access in both directions in very few places.
even with Flitwicks fibre, the speeds are up and down like a yoyo - 1 minute 32 meg, then down to 2, up to 13. there is no stability...
would you really rely on the Cloud as it currently is???
