Here you go - a glimpse at the widgets you'll have access to once you receive the Cupcake update, over-the-air. The process begins on May 11th, and you should get hit within a week or so. I missed out on the Paypal widget because it wasn't available for me until after this video was uploaded.
I don't know if any of you will remember this, but rooting fixed a problem I had with some apps not showing up in the Market. It looks like different builds have this problem to different degrees. Or maybe apps get rolled out to various Market servers, one at a time. Beats me.
What happens when you run two homes and waaaay too many widgets? See below.
