The T4 in my opinion is a great remote, but here are some
of my cons:

- SIZE (very large, 2 handed remote) Not incredibly easy
to handle
- Virtually NO hard keys
- NO 2 Way communication
- Web/Wireless is not really good for much except sports/weather.
- Large price tag
- not mountable at this time
- occasional freezeups even with the upgrade
- unclear to what the Flash upgrade benefits are
- may be obsolete after next generation RTI remotes come
to market.
