Likewise! Since I posted that I saw a Sky News piece which said it will be much worse for servers than normal PCs but it can't help.
Thinking selfishly about my own computers I have a vastly overpowered Chromebook and a fairly overpowered Hackintosh, so I reckon I'll be OK but still annoying.
Is this as bad as it sounds? It sounds pretty bad.
