Received my notifaction last night that my Flipboard invitation for iPad was received and I'm set to go. I'll set up my Twitter feed to it today and see how it looks.
So far what I've seen from Flipboard is nothing short of amazing. They got some bad press last week when there weren't able to handle the onslaught of people trying to use Flipboard. They made some adjustments and are ready to go now, at least for me. Review next week.
