I have an app in the iOS photography category ranked about 100 in sales on iPhone and iPad. My monthly sales are $6000.00 US (after apple's cut) selling for 2.99. Not bad, I'm happy and all, but it's disappointing to think that there are only 100 developers in the photography category making more than 6000.00/mo (assuming that they have only one app) The user interface that iTunes provides on the phone, tablet and desktop is super clunky and slow for exploring apps. Click, wait, click, wait. etc. Why no tabbed browsing so users can load and look at 50 app descriptions in the background?
