you will notice immediately if you do any stylus writing with your Transformer Prime that the screen sensitivity sucks for jotting down notes. I highly recommend TouchScreen Tune to increase the sensitivity. it works awesome!. FYI, your tablet must be rooted to use it. The tablets usefullness is greatly expanded once the screen sensitivity is increased, IMO.
Also FYI, Pocket is the new name for Read It Later. A rebranding of sorts for an awesome app that you should find very handy as already suggested.
One more suggestion would be a replacement browser. I suggest Dolphin Browser. if you do go with the Dolphin browser be sure to grab the "web to pdf" addon. its all free and it is extremely usefull to have as well.
