Bill Thompson’s most recent BBC column cast a sceptical eye on ‘cloud computing’. “In the real world”, he wrote, “national borders, commercial rivalries and political imperatives all come into play, turning the cloud into a miasma as heavy with menace as the fog over the Grimpen Mire that concealed the Hound of the Baskervilles in Arthur Conan Doyle’s story”.

Quite so. You’d have thought that this rather undermines Nick Carr’s confident prediction of the inevitability of ‘computing as a utility’, so one expected that he would pick up Bill’s piece on his blog. Which indeed he has. But he’s oddly uncommunicative about it, confining himself just to summarising Bill’s views. Or am I missing something?
