From what I've seen, Cover is the way to go to minimize the hopping from app to app and making all work on Droid more integrated - it's multitasking taken to a new level. Quite impressive. Anything that minimizes button and touch screen presses is OK with me.
Just an update. Last I heard testing may start at end of week. I asked about tab usage and I have been told that it will run on tabs but designed primarily for one handed use. I'll include tab positives only in review once I get it.
Doesn't seem fair to ding an app if it doesn't perform as well on tabs.
