I use Google Reader to follow thousands of RSS feeds every day, and rely heavily on these two apps to do that on the tablet.
gReader Pro for Android left vs. Reeder for iPad on the right
Reeder is much more visually appealing of the two and operates more smoothly than the Android app.
Skitch is a simple image tool that is available on both the iPad and Android. Both apps are very similar, but the interface controls on the Android app (left) are split between the left and right margins on the screen. The iPad app (right) has all of the controls on the left margin, making them easier to operate by touch.
These two news apps use a magazine layout approach.
Feedly Android (left) vs. Zite iPad (right)
Zite is in a league by itself as it is one of the best apps on my platform. It produces a solid magazine from my preferred news sources and is outstanding in both function and design.
Feedly is a close second, but not as visually appealing as Zite.
