I too am disappointed in the slow development, having moved from BB to iPhone over a year ago. But, in spite of much searching, I have not been able to find an equal to Rex. The iPhone input is more cumbersome than it was on my BB and IdeaMatrix is non-existent, BUT, that I can find, Rex is the only one that allows multiple dimensions (delegate, priority & @context; for example, Chief of Staff, Critical, Cabinet). This allows me to print one report for my Chief of Staff sorted by priorities, and another report for use as an agenda for my cabinet meetings sorted by priority for all members). I work in higher ed and the value add is significant from this tool. My Exec Asst can even log in for me and print for entire staff. Since I switched to Apple products for iCloud I have looked in detail at the other products (Evernote, Omnifocus, Todo, etc.), all very good but not for multiple dimensions and reporting.
