Remote desktop is the best use I've had for larger display resolution. When I can access my desktop at home I can do anything on the RedFly that I coul do at home. Some tasks, frankly, are too painful to do this way, and 800x600 is too limiting for some tasks (Flash, PhotoShop etc) but in the case of an emergency client requirement, anything i spossible
We are still limited by what the Phone can do, i terms of graphics and processor, but over the next year we'll see 800MHz, 1000MHz chips, with the inclusion of dedicated graphocs chips and even quad-core mobile processors ont he horizon too. Once those are mainstream, it should be possible to kick the RedFly up to 1024x768 and higher, even if it is necesary to enable screen scrolling.
