Ok so I have had a mac for a couple of years, but I have no idea what a widget or dashboard is. I have a 1st generation mini and I dont even know about the dashboard and all of that stuff. I keep hearing about widgets and stuff and I was looking online for an ebay tool to use for my mac and I kept being brought back to yahoo widgets. I'm confused. How do I access the dashboard easily? What's a widget? Which ones are useful and does the new mbp come with some already?
