I've been using Journal Bar for over a year now. (First on my X5 Advanced, and now on my X3i.)
In general, I love the concept, and I love the weather imagery on the today screen...BUT...I've recently shut-off all content except for weather and the TV listing page. The regular content would eat up memory and freeze my PIE when I'd attempt to read a story linked to the headline.
I've also added more content on Avantgo, and am sending that content to my SD card (thanks to RegKing freeware:
http://www.cewindows.net/applications/regking2003.htm), rather than my internal memory. Also, I use Mobipocket free reader for similar reasons--i.e., content saved to SD card.
I still love those weather images on the today screen, though. (I even tried TodayPlus to see if I liked their weather today screen images, but I went back to Jouranal Bar.)
I'm hoping that one day, they'll get Journal Bar right, and my free upgrades will come in handy.
