Good choices guys!
On the Dashboard front, widget must-haves are:

• Screenshot Plus - no need to contort your fingers to do a screenshot, just pull up this widget and point-and-click away. Its even far better than having a PrntScn key
• Gmail Widget - check your Inbox at a glance
• Digg Widget - follow the latest diggs
• xCuts - for people who prefer to use keyboard shortcuts. A quick lookup list.
• Gas - get the low-down on the cheapest gas in your area
