If you like charting there’s a pretty good pay app called iChartist Pro. Lots of customization available for the charts etc. That, bloomberg and cnbc are probably the only finance related apps I use on the ipad.
I have the iPad version of iChartist pro. It’s not perfect, but it was the best charting app I could find when I was looking. I’m still pretty happy with it.
This x1000. I remember carrying CFA textbooks and GMAT materials with me on the plane, what a huge pain in the ass.
Also picked up a nook, so far it’s been a great experience. I miss flipping pages and seeing my reading progress, but the e-ink display replicates paper really well.
