Recently (and I suspect, at all times in the past) I've had trouble focusing with even one epileptic app throbbing in the background, or even redrawing some pointless animation or status update. For me one of the criteria for a desktop program is whether it can be prevented from audibly or visually disturbing me with its desires.<p>It may occasionally mean an impatient peer being upset at the lack of a speedy reply, but my thoughts are guaranteed to be uninterrupted unless the conversation is of sufficient importance to hold my attention after returning to real work.<p>The only 'active' notifications I have are mail and calendar, on my phone, which can be silenced temporarily with a single swipe. On the desktop, the only notification is Adium's small, static icon in the menu bar, which raises its wings to politely remind me of some ongoing IM.<p>I'd suggest disabling that almost pointless thermal monitor and the many similarly looking distracting icons long before I'd hide the clock, as it's the only reliable gauge of progress throughout the day.
