Jacob, the main difference I think that he is pointing out is that the Palm OS on the Treos has been optimized a lot more for operation with the 5-way controller........ since this has been a common device on Palm OS devices the past few years, it's also fairly common to find a lot more third party software that can be navigated with just the 5-way controller (we're mainly talking here about things like scrolling, navigating to different buttons and links on the screen, etc.). I only have a Treo 650, but it sounds like what he is saying is that the problem with the Treo 700 is that the 5-way controller isn't as useful for some parts of Windows Mobile (which isn't surprising, of course). Generally speaking, it's true that the stylus is still the most efficient way of navigation, but with a smartphone especially, quick one-handed operation can be pretty handy, and it is nice to be able to quickly whip out your Treo and navigate around it with just the controller without having to take out the stylus and use your other hand as well. I'm sure though that Palm will continue working on this, and if the Treo 700 does prove popular, hopefully Treo-specific support in third party Windows Mobile apps will become more common as well.
