If proper software was made for the Ipaq 3900 series it would be a clear winner but without it the Pronto Pro is still a strong contender, because of it's software, hard buttons and Ir range. Dont get me wrong, in terms of hardware a (long range Ir) equiped PDA is vastly superior but software is our biggest problem, "TV Remote" is a long way off from being the Pronto Killer that it could be.
