My company were nice enough to give us branded advent calendars (unfortunately not as impressive as snoogs - it wouldn't really promote work now would it?) so I thought I'd start a collection of the inevitable electronic ones we'll all start receiving today (or soon anyway)...

Very good business analysis of 'Christmas'...
