Steam Cloud is great. Spending a lunch hour playing Deus Ex:
Human Revolution, able to pick straight up at the point that you left
off last night at home, is the way all games should be. Unfortunately,
not all Steam published games make use of this feature. If you want to
spend an hour tidying your bookshelves in Skyrim, for example, you’ll
need to wait until you get back to your real home or faff around with
memory sticks.
